Answer:

e. All of the above are correct.

Explanation:

Active transport is a type of transport in living systems in which molecules/ions/substances are moved or transported against their concentration gradient i.e. from a region where the substance is LOW to a region which it is HIGH, across a membrane. Since molecules are transported across a memembrane against their concentration gradient, an energy input in form of ATP is needed to do so.

Active transport is used in living systems to transport out secretory products and waste material against concentration gradients, take up nutrients from the environment against concentrations gradients etc. Since ions are substance moved by active transport from a low region to high region, there is an imbalance in the intracellular concentration of ions, such as Na, K etc.

Since there is no equilibrium in the concentration of ions on opposite sides of the membrane, an electric potential is formed across the membrane i.e. one part of the membrane will be more positively charged than the other.

the prime role is that plants take carbon and it helps to make our life clean and stop increasing carbon that cause global warming and plants give us oxygen and take carbon by photosynthesis to make their food and when plants die maybe it turns to fossil fuel that be made from carbon like coal and petroleum

The modern order Squamata, which includes lizards and snakes, likely descended from the fossil reptile group known as the "diapsids."

Diapsids were a diverse group of reptiles that emerged during the late Paleozoic era. They were characterized by having two openings on each side of their skulls, known as temporal fenestrae.

Over time, the diapsids diversified into various lineages, including the archosaurs (which gave rise to dinosaurs and birds) and the lepidosaurs (which gave rise to modern lizards and snakes). The exact evolutionary lineage from diapsids to Squamata is complex and involves several transitional forms.

However, evidence from fossil records and comparative anatomy supports the idea that Squamata evolved from within the diapsid group, specifically from lepidosaurs, during the Mesozoic era.

The correct option is D :Chylomicrons are very large lipoproteins that transport lipids from the intestinal tract and are released into the circulating venous blood at the jugular and subclavian veins.

They are predominantly composed of triglycerides and phospholipids (9%), cholesterol (3%), and apoprotein (1%). When blood passes through the capillaries of different tissues, including adipose tissue, skeletal muscle, and the heart, the majority of chylomicrons are eliminated. As a result, the lipoproteins known as chylomicrons are responsible for transporting absorbed fats from the digestive tract to the blood.

These particles, which are derived from VLDL and IDL particles, have even more cholesterol added to them. The majority of the cholesterol in the blood is carried by LDL. Each LDL particle contains one Apo B-100 molecule, which is the most common apolipoprotein.

\(\huge\textbf{Cellular Respiration:}\)

Cellular respiration is the process through which cells convert sugars into energy. The energy comes from the fuel molecules such as Glucose(sugar) or Lipids(fats). In cellular respiration, Glucose molecule is dismantled in the presence of oxygen. The bonds between the glucose break forming a simpler molecule and energy is released in small amounts. Some of the energy is stored by cell in the form of ATP while rest is lost as heat. So, ATP is formed from glucose through endergonic and exergonic reactions. The aerobic breakdown of glucose molecule accompanying synthesis of ATP is called celluar respiration. Carbon dioxide and water are produced as Waste Products.  

\(C_6H_{12}O_6\ +\ 6O_2\ {\longrightarrow}\ 6CO_2 +\ 6H_2O +\ (ATP + Heat)\)  

These models (the SIM as well as the diagram) are similar because they both depict the fate of energy storage molecules during photosynthesis. However, they also differ since the SIM model shows the products and reactants (time 1, time 2) in the producer cell, whereas, the diagram illustrates the overall reaction during photosynthesis.

The SIM model shows that carbon dioxide and water (reactants) are present within the chloroplast (Time 1) in a producer cell. It also shows the products formed during the process of photosynthesis, i.e. Energy Storage Molecules (ESM) and oxygen, within the chloroplast (Time 2) in the producer cell.

The diagram, on the other hand, illustrates the overall reaction that occurs during photosynthesis as well as the rearrangement of atoms during this reaction. It represents the reaction for photosynthesis which can be also written as:

6 CO₂ + 6 H₂O + light energy → C₆H₁₂O₆ + 6 O₂

Answer: The molar mass

Explanation:

Answer:Frameshift or Missence mutation

Explanation:

After a major event at 120 generations, an allele was lost from the population. In terms of diversity, this left the population with less genetic diversity.

An allele is a variant form of a gene that appears as a result of mutation. An allele is one of the possible alternative forms of a gene that can be present at a given locus (position) on a chromosome. A gene locus refers to a specific location on a chromosome where a particular gene is found.

Genetic diversity refers to the variety of genes and alleles that exist within a population. When a population has high genetic diversity, it implies that it has a wide range of genetic variability, making it easier for the population to adapt to environmental changes. It can also protect the population from disease or predation, increase its chances of survival and persistence, and give it greater resilience against genetic drift, inbreeding, and other factors that can reduce genetic diversity.

Therefore, losing an allele from a population results in a decrease in genetic diversity, which is a disadvantage for the population.

Blood vessels keep clots from sticking as long as their endothelium is intact and healthy, which is option b, as endothelium refers to the inner lining of blood vessels, which is composed of a single layer of cells called endothelial cells.

The endothelial cells have several mechanisms to prevent clot formation. They produce substances such as nitric oxide and prostacyclin, which help to keep the blood flowing smoothly and prevent platelets from sticking together. Additionally, the endothelium produces anticoagulant molecules that inhibit the clotting process, such as heparin-like molecules and tissue factor pathway inhibitors. When the endothelium is intact and healthy, it maintains a non-sticky surface that prevents the formation of clots within the blood vessels.

The three true statements about crossing over are a), c), and e).  

During prophase I of meiosis I, homologous paternal and maternal chromosomes pair up and undergo crossing over, resulting in the exchange of genetic material between the two chromosomes. This process can create new combinations of alleles and increase genetic diversity in offspring.

A hybrid chromosome that has crossed over will contain pieces of both the maternal and paternal chromosomes, as segments of DNA are exchanged during the process. This can result in novel gene combinations that were not present in either parent.

Chiasmata, which are formed by the physical connection between nonsister chromatids during crossing over, increase the genetic variability produced during this process. This is because chiasmata can result in the exchange of larger segments of DNA, leading to more diverse offspring.

Statements b) and d) are false. During meiosis II, sister chromatids separate into two different gametes, not four. Crossing over occurs during meiosis I, not after fertilization occurs.

Answer:

Absorption: The process of absorbing nutrients occurs primarily in the small intestine. Once the food is broken down into smaller molecules through digestion, these molecules are absorbed into the bloodstream. For example, carbohydrates are broken down into simple sugars, proteins into amino acids, and fats into fatty acids and glycerol.

Circulatory System: The circulatory system, composed of the heart, blood vessels, and blood, plays a crucial role in transporting absorbed nutrients. The blood vessels form an extensive network that reaches all tissues and organs in the body.

Hepatic Portal System: After absorption, most of the nutrients are transported to the liver through a specialized system called the hepatic portal system. This system ensures that the liver, which performs various metabolic functions, receives a concentrated supply of nutrients before they are distributed throughout the body.

Bloodstream Transport: Once in the bloodstream, nutrients are carried by the plasma, the liquid component of blood. Different nutrients use specific mechanisms for transport:

Glucose: It is transported by facilitated diffusion or active transport, depending on the concentration gradient, with the help of insulin.

Amino Acids: They are transported through the bloodstream by specific carrier proteins.

Fats: Dietary fats are initially packaged into structures called chylomicrons and transported through the lymphatic system before entering the bloodstream. Once in the bloodstream, fats are carried by lipoproteins such as low-density lipoprotein (LDL) and high-density lipoprotein (HDL).

Distribution to Tissues: As the blood circulates, nutrients are distributed to various tissues and organs according to their specific needs. Nutrients are delivered to cells through the capillaries, the smallest blood vessels in the body, which have thin walls that allow for the efficient exchange of nutrients and waste products.

Cellular Uptake: Nutrients are taken up by cells through various mechanisms. For instance, glucose enters cells with the help of insulin, while amino acids are transported into cells through specific carrier proteins. Fats are taken up by cells through receptor-mediated endocytosis or by diffusion.

Metabolism: Once inside the cells, nutrients undergo metabolic processes to produce energy or build new molecules. Glucose, for example, can be metabolized through glycolysis, the Krebs cycle, and oxidative phosphorylation to generate ATP, the cell's energy currency.

Waste Removal: Metabolic byproducts, such as carbon dioxide and urea, are generated during nutrient metabolism. These waste products are transported back into the bloodstream and eventually eliminated from the body through the lungs (carbon dioxide) or the kidneys (urea).

It's important to note that different nutrients may have different transport mechanisms and pathways. The body's ability to efficiently transport and utilize absorbed nutrients is vital for maintaining proper functioning and overall health.

Due to their apparent similarity in form, function, and behaviour, analogous structures and homologous structures are frequently mistaken for one another. Homology refers to similarity at all levels due to a shared origin (organism, population and species). Genealogs known as homoplasts do not have a common ancestor among species. Homoplasy is resemblance resulting from a shared ancestry at the organism and population levels but not at the species level.

All three statements provided are true regarding joints, fractures, folds, tilting, and shear zones:

1. Fault blocks created by a series of faults may rotate and tilt: This statement is true because when a series of faults occur, the fault blocks, or pieces of the Earth's crust, can shift in different directions.

This movement can cause the blocks to rotate or tilt relative to one another as a result of the forces acting on them.

2. Joints and folds are common along faults: This statement is true because joints, which are fractures or breaks in rocks with no significant movement, often form in response to the same stresses that produce faults.

Folds, which are bends or deformations in rock layers, can also form due to the compression or tension forces acting on rocks along faults. As a result, both joints and folds can be found in close proximity to fault zones.

3. During displacement in a shear zone, rocks may fold and stretch layers: This statement is true because a shear zone is an area where rocks have been deformed due to shear stress, or forces acting parallel to the rock layers.

As rocks are displaced within the shear zone, the layers can fold and stretch, resulting in changes to the original shape and orientation of the rock layers.
