Describe what must happen for fertilisation to take place in humans.

Answers

In the process of sexual reproduction, mating of male gamete and female gamete is required for the fertilization to take place in humans.

A gamete is an animal or plant reproductive cell. Male gametes in animals are known as sperm, while female gametes are known as ova or egg cells.

Fertilization is the process in which a woman's egg combines with a man's sperm to form an embryo.

Usually, the fallopian tube that connects an ovary to the uterus is where fertilization occurs. An embryo begins to develop if the fertilized egg successfully passes through the fallopian tube and implants in the uterus.

Do plants take in air with their roots?

Answers

Answer:

No

Explanation:

No, plants do not take in air with their roots. Roots are designed to absorb water and minerals from the soil. In order to get the air and carbon dioxide they need for photosynthesis, plants have specialized structures called stomata in their leaves and stems that allow air to enter and exit. These stomata regulate the movement of gases into and out of the plant, so the plant can take in the carbon dioxide it needs and release the oxygen it produces.

How does kelp obtain food? (Describe the whole process of photosynthesis including inputs and outputs, equation for photosynthesis, the type of energy going in and out, where in the cells of kelp this occurs)

Answers

Kelp obtains food through the process of photosynthesis, which occurs in specialized cells called chloroplasts located within its blades.

How does kelp obtain food?

The photosynthesis process begins when kelp absorbs sunlight, which provides the energy needed to power the process. Specifically, the light energy is absorbed by a green pigment called chlorophyll, which is located within the chloroplasts.

Next, carbon dioxide (CO2) from the surrounding water is taken up by the kelp through small pores called stomata, which are located on the surface of the blades. The CO2 combines with water (H2O) that has been absorbed by the kelp's root-like structure called the holdfast. Together, the CO2 and H2O react in the presence of light and chlorophyll to produce glucose (C6H12O6) and oxygen (O2) as byproducts.

In summary, kelp obtains food through the process of photosynthesis, which involves the absorption of light energy by chlorophyll, the uptake of CO2 and H2O, and the production of glucose and oxygen. This process occurs within the chloroplasts located in the blades of the kelp.

Which of the following are a part of the circulatory system? I. Blood II. Lungs III. Heart IV. Blood Vessels A. I, II, III, and IV B. II, III, and IV C. I, III, and IV D. I and IV

Answers

Option A is correct as I, II, III, and IV are all a part of the circulatory

system.

The circulatory system, also known as the cardiovascular system, is a complex network of organs and vessels responsible for transporting blood, oxygen, nutrients, hormones, and other necessary substances to different parts of the body. It also plays an important role in the removal of metabolic waste and carbon dioxide from the body.

I. Blood is a vital component of the circulatory system that flows through the blood vessels and carries oxygen, nutrients, hormones, and other substances to different parts of the body.

II. Lungs are also a part of the circulatory system as they help to oxygenate the blood by allowing oxygen from the air to enter the bloodstream and carbon dioxide to be eliminated from it.

III. Heart is a muscular organ that pumps blood to the entire body. It is the center of the circulatory system and also responsible for regulating blood pressure.

IV. Blood Vessels include arteries, veins, and capillaries. Arteries carry oxygen-rich blood from the heart to the body and veins return oxygen-poor blood to the heart. Capillaries are small, thin-walled vessels where the exchange of oxygen, nutrients, and other substances takes place between the blood and the tissues.(option-a)

Decide if the function is an exponential growth function or exponential decay function, and describe its end behavior using limits.

Answers

Function is an exponential growth function or exponential decay function  it is an exponential decay function, as it starts at infinity and ends at 0.

For exponential functions, we see that our end behavior goes to infinity as our input values get larger. The larger the base of our exponential function, the faster the growth. For logarithmic functions, our function grows slowly as our input values get larger.

Examples of such phenomena include the studies of populations, bacteria, the AIDS virus, radioactive substances, electricity, temperatures and credit payments, to mention a few. Any quantity that grows or decays by a fixed percent at regular intervals is said to possess exponential growth or exponential decay.

Based on the shape of the exponential decay graph, we have the following end behavior: As , x → − ∞ , . y → ∞ . As , x → ∞.

Od
Ductus venosus; right atrium; vena cava
Ductus venosus; vena cava; right atrium
Ductus arteriosus; right ventricle; aorta
Ductus arteriosus; aorta; right ventricle

Answers

A red blood cell in the umbilical vein of a fetus will flow next in the proper order as follows: Ductus venosus; vena cava; right atrium.The ductus venosus is a blood vessel that connects the umbilical vein to the inferior vena cava.

It allows oxygenated blood from the placenta to bypass the liver and enter the systemic circulation of the fetus. The red blood cell will pass through the ductus venosus, which acts as a shunt, directing the oxygenated blood towards the vena cava.

From the vena cava, the blood will enter the right atrium, which is one of the four chambers of the fetal heart. The right atrium receives deoxygenated blood from the body and the oxygenated blood from the umbilical vein.Finally, the blood will leave the right atrium and continue its circulation through the fetal heart, where it will be pumped to the lungs for oxygenation.

However, since the lungs are not fully functional in the womb, the blood is redirected through the foramen ovale and ductus arteriosus to bypass the pulmonary circulation.In summary, the correct order of flow for the red blood cell in the umbilical vein of a fetus is: Ductus venosus; vena cava; right atrium.

A crane has a sharp and pointed beak while the duck has a flat beak.Explain why

Answers

Answer:

The crane has a sharp and pointed beak adapted for catching and grasping prey. The sharp beak allows the crane to effectively stab and pierce its prey, such as fish, frogs, or small animals. The pointed shape helps the crane to accurately target its prey and secure a firm grip.

On the other hand, the duck has a flat beak, which is better suited for its specific feeding habits. Ducks are primarily filter feeders, and their flat beak enables them to sift through water or mud to collect small organisms, insects, and plants. The flat beak acts like a sieve, allowing the duck to strain out food particles while retaining water.

The difference in beak shape between the crane and the duck reflects their distinct feeding strategies and ecological roles. Each species has evolved its beak shape to optimize its ability to capture and consume the specific types of food sources available in their respective habitats.

Identify when mutations that involve DNA coding to Amino Acids occur when

Answers

Mutations that involve DNA coding to amino acids occur during the process of transcription and translation.

What is mutation?

A mutation is a permanent change in the DNA sequence that makes up a gene. Mutations can occur spontaneously, or they can be caused by exposure to certain environmental factors, such as radiation or chemical mutagens. Mutations can be beneficial, harmful, or have no effect on the organism, depending on the nature and location of the change in the DNA sequence.

Mutations can result in the creation of new traits or the loss of existing traits, and they play an important role in evolution. Some mutations can lead to genetic disorders or diseases, while others can have no effect on the organism. Mutations can also be passed down from generation to generation, making them an important factor in the inheritance of traits and the evolution of species.
