Droughts occur due to climate change and elevated temperatures, which in turn may lead to other consequences as well. Imagine that a wildfire happened in the nature reserve. Predict what would happen if such an environmental shift that is so extreme and rapid
hits the nature reserve and the population of deer mice does not have time to adapt. Propose a possible solution for this problem.
Answer:
Research shows that changes in climate create warmer, drier conditions. Increased drought, and a longer fire season are boosting these increases in wildfire risk. ... Changes in climate add to these factors and are expected to continue to increase the area affected by wildfires in the United States.

The most important feature that permits a gene to act as a molecular clock is The most important feature that permits a gene to act as a molecular clock is having a reliable average rate of mutation. having a larger proportion of exonic DNA than of intronic DNA. its being acted upon by natural selection. having a large number of base pairs. its recent origin by a gene duplication event
Answer:
The answer is "The first choice".
Explanation:
The hypothesis of such a molecular clock says because DNA and protein sequences develop at a pace generally constant over time as well as between different organisms. The whole idea is thus incredibly beneficial and for estimation of the historical periods, if the molecular biological hypothesis is valid, then the most significant feature enabling DNA to act as a molecular clock it has a reliable mean mutation.
An epistatic allele in labrador retrievers ensures that ee lab pups are yellow. Two other alleles control coat color, where black is dominant to brown. What portion of yellow pups would you expect from a parental cross where one parent was yellow (Bbee) and the other was heterozygous
Answer:
1/4
Explanation:
Epistasis is defined as a phenomenon in a genetics where the effect of the gene mutation which dependent on the absence or the presence of the mutation in more than one genes.
In the context, an epistatic allele in the Labrador retrievers which ensures the ee lab pups that are yellow and the two other alleles which control coat color are black that is dominant to the brown.
Thus, 1/4 portion of the yellow pups would expect from the parental cross where one of the parent is yellow (Bbee) and the other is heterozygous.
Thus the answer is 1/4.
Adults produce gametes through a type of cellular reproduction called mitosis. The process of a sperm cell and an egg cell fusing together is called fertilizationand produces a zygote. As a zygote undergoes rapid cell division to develop into an embryo, fetus, and eventually baby, the type of cellular reproduction being used is . As a baby grows into an adult, the type of cellular reproduction used is mitosis.
Answer:
Mitosis.
Explanation:
Mitosis is the type of cellular reproduction which is used in order to develop an embryo, fetus, and eventually baby. In mitosis type of cell division, the parent and mature cells divides into two daughter cell. This type of cell division occurs in somatic or body cells whereas meiosis type of cell division occurs in the sex cells which produces four daughter cells from a single parent cell.

In non-muscle cells, a small increase in the cytosolic concentration of Ca2 can have a dramatic effect on several physiological processes. The presence of a specific protein in the cytosol, however, activates a Ca2 ATPase that serves to return these elevated cytosolic Ca2 levels back to basal levels, thereby maintaining the cell's normal physiology. Which protein is directly involved in activating this Ca2 ATPase
Answer:
calmodulin
Explanation:
The calcium-modulated protein (calmodulin) is a calcium-binding receptor protein that modulates contractile proteins (i.e., actin and myosin proteins) of the skeletal muscle and non-muscle cells (e.g., platelets). Calmodulin binds to calcium ions (Ca2+) and subsequently activates a number of Ca2+ dependent enzymes (e.g., kinases or phosphatases), which finally activate/deactivate proteins in the calcium signal transduction pathway. Ca2+-ATPase pumps in the membranes of eukaryotic cells release Ca2+ from the cytoplasm and they are autoinhibited by low Ca2+ levels, while calmodulin-binding releases this autoinhibition and thus activates the pumps. In non-muscle cells such as platelets, calmodulin also mediates Ca2+ control of actin-myosin interaction by phosphorylation of the myosin light chain (MLC).
where does pollination takes place in the flower
Answer:
To be pollinated, pollen must be moved from a stamen to the stigma. When pollen from a plant's stamen is transferred to that same plant's stigma, it is called self-pollination. When pollen from a plant's stamen is transferred to a different plant's stigma, it is called cross-pollination.

Do you think if the environmental conditions in an area changes that the plants and animals that inhabit that region will change their features to adapt to the changing conditions?
Answer:
yea
Explanation:
cause our climate conditions changes everyday depends on the atmosphere at that time so if there fire in a forest all the animals there have to adapt to the smoke.
Yes, if the environmental conditions in an area changes that the plants and animals that inhabit that region will change their features to adapt to the changing conditions.
Why plants and animals will change their features?
Plants and animals are fundamentally different in many ways, but one of the most obvious is in how they deal with temperature.The climatic niche of a species reflects where it can live.A species with a wide climatic niche can range widely across many different conditions and may be especially resilient to climate change.Different sets of plant and animal species tend to occur at different elevations, which differ in temperature and precipitation.

In humans, brown eyes are dominant to
blue eyes. What is the probability
that two heterozygous brown-eyed
parents will have a child with blue
eyes?
J. 25%
K. 50%
L. 75%
M. 100%
Answer:
j
Explanation:
since brown eyes are more dominant than blue eyes chances of it is 3/4
Answer:
The answer is J. 25%.
Explanation:
In this problem, we know brown eyes are dominant to blue eyes. We can let the dominant allele for brown eyes be represented by "B" and the recessive allele for blue eyes be represented by "b". Since it is given that both parents are heterozygous, we know that they must have the genotype Bb.
When two Bb individuals are crossed, the offspring will be 1 BB : 2 Bb : 1 bb, or 3 brown : 1 blue ratio. Therefore, 1/4 of the offspring will have blue eyes, which represents 25%. Thus, the correct answer is choice J, 25%.

HELP! What evidence indicates that many psychological disorders, such as schizophrenia and developmental
disorders, are biologically and not environmentally based?
Answer:
Schizophrenia and developmental disorders are traced genetically, and the gene will be found in the biological parents of the person with either schizophrenia or developmental disorders.
Explanation:
Although Schizophrenia can be triggered by environmental factors, or the 'nurture' of childhood development, a person who is not predisposed genetically to schizophrenia will not get the psychological disorder. The same is to be said about developmental disorders such as Autism and ADHD, it is hereditary.
For citation of evidence, I recommend talking about prenatal development, and how toxic substances can alter the development of a fetus, which is proven to lead to some developmental disorders, such as Fetal Alcohol Syndrome.
Answer:
Schizophrenia and developmental disorders are genetically connected, and the gene will be found in either the individual's biological parents or the person suffering from schizophrenia or developmental abnormalities.

Hello. Unfortunately your question is incomplete, which makes it impossible for it to be answered. However, through the context, we can see that your question is asking you to describe the cellular structures that you can see through a microscope.
To answer this question, you will need to look at biological material under a microscope to see what cells this material has and the structures it has. To do this, you will need to determine what material you will be using. This material can be a leaf, flower, a piece of fruit, or any other material that contains cells. After choosing the material, you need to search for a protocol, a tutorial, that shows how this material can be prepared so that the cells can be visualized through a microscope. This protocol can be found on the internet and in articles. You must follow the entire protocol to the letter, to be able to identify the cellular structures.
