Answer:
Likewise, competition for food among deep-water fish that eat the same types of food will .
Explanation:
Natural selection will condemn all deep-sea fish to the same environment that conditions them, those that cannot develop gills will be exposed to extinction, this refers to the theory of the evolution of the fittest by Charles Darwin.
Answer:
A species of fish evolved over thousands of years to have gills that allowed the fish to swim deep in the sea. What’s the effect of this development on deep-water resources?
The fish developed the gills because of
genetic modification
. Because the fish are now able to swim in deep water, their
predators
in shallower water will have less food. Likewise, competition for food among deep-water fish that eat the same types of food will
decrease

Deer need food and water to survive. What are food and water for the deer population?
carrying capacity
limiting factors
population growth
scarce resources
Deer need food and water to survive, and these resources are essential for the deer population to thrive.
Where water can be found?Water can be found in streams, lakes, and ponds, and food for deer populations can include grass, leaves, twigs, fruits, and nuts. Carrying capacity, limiting variables, population increase, and scarce resources can all have an impact on the availability of these resources.
The greatest number of deer that a particular ecosystem can support is known as carrying capacity. If the deer population surpasses the carrying capacity, resources will become scarce and the population will begin to drop.
This is determined by the amount of food and water available in the area. Disease, predation, and human hunting are limiting variables that can also have an impact on the deer population's size and the amount of food and water they have access to.
Population growth is also an important factor, as when the population grows too quickly, the resources may become scarce and the deer will struggle to survive. Finally, scarce resources can also affect the deer population, as when resources are not readily available, the deer will have to compete for food and water, leading to a decrease in their population.

Which of the following is an example of haploid cells? cardiac cells nerve cells gametes muscle cells
Answer:
Gametes is an example of haploid cells.
Explanation:
Haploid cells are cells that contain a single complete set of chromosomes. Haploid cells in humans and other mammals, are usually the sex cells (egg and sperms) which are also called gametes that are produced during meiosis (a type of cell division). When the egg is fertilized by a sperm, it produces a diploid cell. Gametes contain 23 chromosomes in humans.

Answer:
Classification is a systematic ordering of the object of research, in this case, ecosystems at the earth's surface or, in other words: landscape units as 'holons'. As for general principles of classification, we can learn a lot from the best-known classification, the taxonomical classification of species.
Explanation:
A 68-year-old woman who presents after a fall reports progressive difficulty climbing stairs for the past 3 months. She also feels a loss balance when rising from a chair. She has a 5-year history of diabetes mellitus for which she takes metformin. Examination demonstrates intact cranial nerve function; normal sensory examination except for mildly decreased touch and vibration in her toes, normal motor function except for 4+/5 deltoid power and 4+/5 hip power bilaterally, and an inability to stand on her toes. Deep tendon reflexes are 2+ but 1+ at the ankles; plantar responses are flexor; cerebellar function is normal except for mild difficulty with heel-knee-shin testing. She has difficulty rising from a chair without pushing up with her hands. These clinical findings are best explained by dysfunction in which of the following regions of the nervous system?A. anterior horn cellB. muscleC. nerve plexusD. peripheral nerveE. spinal cord
Answer:
spinal cord and nerve plexus
Explanation:
Faced with this clinical picture, we would be talking about the affection of the spinal cord and the peripheral nerves that sensually perceive the areas of the epithelium, that is, they give the sense of touch, since the patient is diabetic, it could be deduced that the microangiopathies that this generates Chronic disease over time, can affect the irrigation of certain areas and therefore their inventions, due to lack of supply of oxygen and nutrients.
Diabetics are at risk of affecting both upper and lower limbs, because over time they lose the vascularization and winterization of these areas, thus generating infections or pain imperceptible by the patient.
On the other hand then, it would be ideal to say that the spinal cord with the peripheral nerves that innervate the affected areas, and the cerebellum are affected by the lack of balance or spatial disposition of the patient in relation to their body size.

A student experiments with two solutions containing the same solute concentrations
in a beaker that is divided by a semipermeable membrane, as shown.
In which direction will the water move so that the concentrations of the solutions
remain constant on both sides of the membrane?
A in both directions at different rates
B in both directions at the same rates
C toward the right side of the beaker
D toward the left side of the beaker
Answer:
B in both directions at the same rates
Explanation:
Solutions with the same amount of solute concentration is referred to as ISOTONIC. In an isotonic solution, there is NO net movement of water molecules because there is no osmotic gradient i.e. difference in solute concentrations.
In this case, a student experiments with two solutions containing the SAME SOLUTE CONCENTRATIONS in a beaker that is divided by a semipermeable membrane. Due to the equal amount of solute concentrations in both solutions, water moves into and out each membrane at an equal rate.
In order for the concentrations of the solutions to remain constant on both sides of the membrane, WATER MUST MOVE IN BOTH DIRECTIONS AT THE SAME RATE.

In other cases, researchers use natural experiments in which the dependent variable (typically a measure of organism health) is measured under differing contexts that are not manipulated. Say, for example, that an accidental chemical spill contaminates five ponds. To determine the possible effects of the toxic chemical on frogs, a researcher could compare the hatching rate of frog eggs laid in those five ponds to the hatching rate of eggs laid in five uncontaminated ponds nearby. This would be an example of a natural experiment because concentrations of the toxic chemical in the ponds were not controlled by the experimenter, but rather resulted from the chemical spill.
Drag type of experiment on the left to the example of experiment on the right.
A. Natural
B. Manipulative

Answer:
1. Natural
2. Natural
3. Manipulative
4. Manipulative
5. Manipulative
6. Manipulative
7. Natural
Explanation:
1. Checking the blood concentration of BPA in college students in relation to their recent consumption of canned food items is a natural experiment because BPA concentration in blood is not artificially controlled by any means.
2. Comparing the feeding behavior of fish in streams with acidic runoff to that of fish in an unaffected stream is a natural experiment due to the fact that the acidity of the stream is not artificially controlled in any way by the experimenter.
3. Checking the deformity rate in baby birds from nests in pesticide-sprayed fields and that from unsprayed fields would require some manipulations except a sprayed and unsprayed one already existed long before the experiment was given birth to. Otherwise, the sprayed field might need to be artificially created just for the purpose of the experiment.
4. A known carcinogen would need to be administered to a group of the mice. This is manipulative.
5. The tadpoles would need to be artificially exposed to the toxic metals in the laboratory. Manipulative
6. The spraying would need to be carried out artificially in order for the comparison to be made. Manipulative
7. People with diabetes cannot be artificially created. They must have existed naturally long before the experimental design. Natural

What percent of their offspring are likely to inherit the disease? if two parents carry a recessive allele for a disease but don’t have it
Answer:
1/4
Explanation:
By saying that both parents have the recessive allele, but don't have it, it tells us that both parents are Heterozygous for this trait. They have one dominant trait and one recessive trait. This is demonstrated in the in the punnett square. We can see that 1/4 of the offspring will have two recessive alleles, 1/2 of the offspring will be Heterozygous, and 1/4 of the offspring will have both dominant alleles. In order to have the disease, the offspring needs to have both recessive alleles. That is 1/4 of the the offspring.
if a prey evolves to increase its defenses, its predator often evolves to counteract this change. a. True b. False
Answer:
a. True
Explanation:
Coevolution is a biological process where pairs of species or among groups of species reciprocally affect each other's evolution through natural selection. This process produces genetic changes in the traits of interacting species that are a consequence of reciprocal adaptation between these interacting taxa. Coevolution occurs when species are ecologically intimate (i.e., they interact with one another), such as the interaction between hosts and parasites or predators and prey.
Which chemical is released by (2) WBC's that produces a non-specific inflammatory response?
Answer:
cytokines
Explanation:
Non-specific immune responses are integral to host cellular defense mechanisms. It is a general response, mediated by white blood cells, where cells rapidly react to pathogenic infiltration.
Here receptors on cells recognise molecules shared by a broad spectrum of pathogens, or even react to signals from damaged, injured or stressed cells like inflammatory cytokines in a cytokine storm.

Answer:
Any organism that eats the blue crab will decline.
Explanation:
If blue crabs dropped out of the food chain, I would expect to see a decline in eels, drums, spots, Atlantic croakers, striped bass, sea trout, and catfish because crabs are an important food source for these organisms. Some sharks, cownose rays, Kemp’s riddley, and loggerhead sea turtles also eat on blue crabs at different stages of life. If blue crabs dropped out of the food chain, it is possible that population with decline in any of these organism from the Bay.
Answer:
You would expect to see a decline in eels, drums, spots, Atlantic croakers, striped bass, sea trout, and catfish because crabs are an important food source. If the dropped of the food chain the predators population will decrease and the secondary and primary organisms will increase
Explanation:
Create an example in which a mutation entered the gene pool and due to predator pressure. Becomes predominate. For example, think about how the color of the Peppered moths during the industrial revolution changed. The moths were light in color, but due to all the pollution from industry the trees they lived on turned dark making the light moths an easy target for birds. The moths with the mutation for dark color were able to blend with the darker bark and survived. These dark colored moths passed their genes on to their offspring and over a relatively short period of time most of the moths became dark. When the pollution decreased, the lighter colored moths predominated once again.
*Write a paragraph or so it can be a little under. Ill give you brainiest.*
Answer:
The population of light colour Peppered moths decreases and dark Peppered moths increases.
Explanation:
During the industrial revolution, the population of light colour Peppered moths decreases and dark Peppered moths increases because due to industrial revolution, air pollution increases which spreads a black dust on the trees and as a result the light colour Peppered moths can easily be seen in the dark by its predator and feed on them while dark colour Peppered moths can't be seen in the dark so the predator is unable to feed and as a result the population of dark colour Peppered moths increases.

Both mitosis and meiosis begin with a diploid cell that contains replicated chromosomes. What are the main differences between these two processes, and what types of daughter cells produced by each? Meiosis has four cell divisions and results in four haploid daughter cells with genetic variation, while mitosis has two cell divisions and results in two identical daughter cells. Meiosis has two cell divisions and results in four haploid daughter cells with genetic variation, while mitosis has one cell division and results in two identical daughter cells. Mitosis occurs in gametes to increase genetic variation in daughter cells, while meiosis occurs in body cells for growth and repair. Mitosis produces genetic variation in daughter cells and increases the number of chromosomes, while meiosis occurs in body cells for growth and repair.
Answer:
Meiosis has two cell divisions and results in four haploid daughter cells with genetic variation, while mitosis has one cell division and results in two identical daughter cells.
The main differences would be that Meiosis has 4 cell divisions and Mitosis had 2 cell divisions. Meiosis results in 4 haploid daughter cells and Mitosis results in 2 identical daughter cells.
Another big difference between the two could be that Meiosis produces genetic variation in the daughter cells and increases the number of chromosomes whilst Meiosis occurs in body cells for growth and repair. Each process has a different job.

Figure 1 show the distributions of the two squirrel species in 1945 and 2010.
Answer:
The grey squirrel has increased their rate of emigration to the UK
The grey squirrel has increased their rate of emigration to the UK.
What is emigration?Emigration is the act of relocating away from a resident country or place of residence (to permanently leave a country). Contrarily, immigration refers to the flow of individuals from one country into another (to permanently move to a country).
A migrant leaves their home nation and moves to their adopted one. Emigration and immigration thus both describe migration, but from the perspectives of various nations.
Demographers look at the push and pull factors that cause people to be drawn to one place and pushed away from another. Desires to escape unfavorable situations, such as scarcity of land or employment opportunities, or unfair treatment, are possible.
Therefore, The grey squirrel has increased their rate of emigration to the UK.
