interpret what data means about the otter’s role in the kelp forest. what is the percent fish in diet? (otters present) what is the percent fish in diet? (otters absent) what is the percent of invertebrates in diet? (otters present) what is the percent of invertebrates in diet? (otters absent)
Answers
In general, otters play a crucial role in maintaining the health of kelp forests. They are considered a keystone species because they feed on sea urchins, which are known to graze on kelp.
Without otters, sea urchin populations can grow unchecked and damage the kelp forest ecosystem. By keeping sea urchin populations under control, otters help maintain the balance between kelp and other organisms in the ecosystem.
The percentage of fish and invertebrates in the otter's diet can vary depending on their location and availability of prey. Otters are known to be opportunistic feeders and will consume a variety of prey depending on what is available. Studies have shown that otters can consume a range of invertebrates, including crabs, clams, and snails, as well as fish species such as rockfish and herring.
In general, when otters are present, there may be a lower percentage of sea urchins and a higher percentage of fish and invertebrates in the ecosystem.
Conversely, when otters are absent, the sea urchin population may grow unchecked, leading to a decline in kelp and potentially impacting other species that rely on the kelp forest ecosystem.

Explanation:
The principle of PT or prothrombin test determines the time required for the clot formation when additional calcium factor is added.
The principle of APTT or activated partial thromboplastin time is a test which determines the time required for the formation of the blood clot after the adding the calcium and phospholipid factors. This process activates the different blood clotting factors in the blood responsible for clotting of blood.

In a dihybrid cross between two pea plants, one parent is green pod-purple flower (GgPp). The other parent’s genotype is unknown. The phenotype f ratio of their offspring is (1 Green Pod-Purple Flower : 1 Yellow Pod-Purple Flower). What is the genotype of the unknown parent?
Answers
The unknown parent's genotype in the dihybrid cross is likely GgPp. This genotype would result in a 1:1 phenotypic ratio of green pod-purple flower to yellow pod-purple flower offspring.
In a dihybrid cross, we consider two independent traits. In this case, the traits are pod color (green or yellow) and flower color (purple). The known parent's genotype is GgPp, where G represents the dominant allele for green pod color, g represents the recessive allele for yellow pod color, P represents the dominant allele for purple flower color, and p represents the recessive allele for non-purple (white) flower color.
Since the phenotypic ratio of the offspring is 1 green pod-purple flower : 1 yellow pod-purple flower, we can infer the possible genotypes of the unknown parent. The observed phenotypic ratio suggests that both parents contribute equally to the offspring's traits. Therefore, the unknown parent likely carries the same genotype, GgPp.When the unknown parent's genotype is GgPp, it means that it can produce two types of gametes: GP and gP. The known parent, GgPp, can also produce two types of gametes: GP and gP. The cross between these parents can result in four possible genotypes for the offspring: GGPp, GgPp, Ggpp, and ggPp. However, only two of these genotypes correspond to the observed phenotypic ratio: GgPp (green pod-purple flower) and ggPp (yellow pod-purple flower).Therefore, the genotype of the unknown parent is likely GgPp, which produces the desired 1:1 phenotypic ratio of green pod-purple flower to yellow pod-purple flower in the offspring.

One risk of introducing a predator or parasite from a different ecosystem is the non-availability of its controlling agent.
What is risk of introducing a predator?When a new and aggressive species is introduced into an ecosystem, one risk is that it may not have any natural predators or controls in that new ecosystem. So it can breed and spread very quickly and the native organisms may not be able to compete with a species that has no predators.

Osmosis, active transport and passive transport are the three ways or methods which is used by the particles to go into or out from the cell membrane.
Describe how the particles will diffuse across the membrane?
In facilitated diffusion, molecules diffuse throughout the plasma membrane with help from membrane proteins, consisting of channels and vendors. A concentration gradient exists for these molecules, so they have the capability to diffuse into (or out of) the cellular by using shifting down it.
The method which is used by the particles to move from the cell membrane are Osmosis, Active transport and Passive transport. So these are the three ways or paths which are used by the particles to move into or out from the cell membrane.

Filaments connected to the dense plaque underlying the membrane in a hemidesmosome course outward into the cytoplasm. These filaments are composed of the protein and are best known as A) actin, microfilaments B) keratin, microfilaments C) actin, intermediate filaments D) keratin, intermediate filaments
Answers
The answer is c) keratin, intermediate filaments.
What are keratin intermediate filaments?In epithelia, keratin intermediate filaments are widely distributed and organize into cytoskeletal networks that support cell type-specific processes like adhesion, migration, and metabolism. These functionalities are maintained via a continuous cycle of keratin filament turnover.The cytoskeleton's main structural element, the intermediate filaments, are made up of a few smaller subgroups as well as the five major subgroups vimentin, keratins, desmin, neurofilaments, and glial fibrillary acidic protein (GFAP) (e.g., nestin, peripherin).A protein called keratin aids in the formation of your skin's outer layer, hair, and nails (epidermis). Your skin is supported, wounds are treated, and your hair and nails are kept in good condition.In contrast to actin filaments and microtubules, intermediate filaments are extremely stable structures that make up the real skeleton of the cell. They provide the cell its elastic qualities and its capacity to tolerate tension. They also anchor and place the nucleus within the cell.Hemidesmosomes are found in the basal membrane of the epithelial cells, which helps to attach to the basal lamina. hemidesmosomes contain integrin proteins it is attached to laminin protein in the basal lamina and in the cytoplasmic side it is attached to intermediate filaments made of keratin.
These filaments are composed of the protein and are best known as actin, intermediate filaments.
Therefore, the answer is c) keratin, intermediate filaments.

Sharon wants to conduct an experiment to determine if increasing the concentration of atmospheric carbon dioxide around a plant will affect the plant's rate of photosynthesis. The correct option is C 4-3-2-1 .
Plants and other living things employ a process called photosynthesis to transform light energy into chemical energy that can then be released through cellular respiration to power the organism's activities. The word "photosynthesis" comes from the Greek words "light" and "putting together," and refers to the process of creating molecules of carbohydrates from carbon dioxide and water. These molecules, such as sugars and starches, are then stored with some of this chemical energy. [1] [2] [3] Photoautotrophs are creatures that perform photosynthesis, including most plants, algae, and cyanobacteria. The majority of the energy required for life on Earth is produced and maintained by photosynthesis, which is also substantially responsible for producing and maintaining the oxygen content of the atmosphere.
Even though various species perform photosynthesis in different ways, the process always starts when energy from light is absorbed by proteins called reaction centers that contain the colored pigments/chromophores green chlorophyll (and other colors). Unlike bacteria, which have these proteins incorporated in the plasma membrane, plants store these proteins in organelles called chloroplasts, which are most prevalent in leaf cells.

The experimenter's chosen variable or variables are considered independent. The anticipated "cause" will be this manipulation. The independent variable's value determines how much the dependent variable is worth.
The result of the cause will be this (if the manipulation succeeds). One group of volunteers receives a medication, while the other receives a placebo. Cancers diminish in the medication group but they do not in the control (placebo) group.
