Describe how 1 specific adaptation will arise in the white tailed deer
Answer:
White-tailed deer are adapting to the environment with their specific color. This way the predators can’t see them. If sometimes the danger is very close, they can freeze and camouflage so that no one can see that they are actually on the spot.
Explanation:
These animals are living in different areas, but the best area for them is a place with dense grass where they can eat. They have many ways of camouflaging in nature, so they are used to avoiding danger. This is why they live longer.

Which of the following best describes the rate of motion of a glacier?
Very quickly
Same as turbidity currents
Very slowly
Same as the speed as continental drift
Answer:
Very slowly
Explanation:
Even it may seem that the glacier is moving rapidly, it moves very slowly. It is a solid block of ice and that ice is making it move, as the pressure on the ice enters the block.
As the ice is melting around the glacier, it helps him slide and move. Glaciers are moving as a response to climate change. The glacier moves the fastest on the points where the ice is thinner and there is no friction. While glacier has enough amount of snow and ice, it will move.

which of the following describes the relationship between population growth and the underground water supply?
A. as the population grows, the water supply remains the same, thus increasing its demand.
B. As the population grows, the water supply is increased due to modern technology.
C. As the population grows, the water supply grows proportionally because of the increased demand.
D. As the population grows, the water supply shrinks due to the increased demand.
D
Usually, with increased population growth, there is a direct increase in demand for resources such as water.
Explanation:
When the demand for water by the population overwhelms the supply from surface sources such as lakes and rivers, underground water is taped. Boreholes are sunk to reached water aquifers.
However, drawing underground water more than it is replenished by precipitation, lowers the water table. As a consequence deeper boreholes have to be sunk to reach more underground water. A critically lowered water table can result in drought in the region.

Based on that information, are the symptoms of someone poisoned with botutism?Explain.
Answer:
The symptoms of someone poisoned with botulism are drooping eyelids , trouble breathing , blurred or double vision, nausea, abdominal cramps , dry mouth , difficulty in speaking or swallowing, facial weakness and muscle weakness resulting in paralysis.
Explanation:
Botulism is caused by botulinum toxin (neurotoxin), which is produced by the bacterium Clostridium botulinum. This toxin blocks the release of the neurotransmitter acetylcholine, prevents it from crossing the neuromuscular junction and binds to muscle fiber receptors. As a result, the nerves are paralyzed and they cannot stimulate the muscle to contract. This causes trouble in breathing, drooping eyelids , blurred or double vision, slurred speech, difficulty in swallowing, facial weakness, nausea, abdominal cramps , dry mouth and muscle weakness which results in flaccid paralysis.

a. symbiosis
c. carrying capacity
b. succession
Succession is the process by which an uncut lawn develops into a meadow and eventually a forest, beginning with pioneer species and progressing to a climax community.
Explanation:The process in which an uncut lawn becomes a meadow and eventually a forest is an example of succession. Succession is the sequential development of plant and animal communities in an area where no soil initially exists (primary succession) or in an area that has been disturbed and contains soil (secondary succession). This ecological process starts with pioneer species, such as grasses, which improve soil quality and allow other plants to move into the area.
Over time, these pioneer species are replaced by subsequent groups of plants and ultimately by a mature community, often a forest in the case of secondary succession. This eventual stable community is known as the climax community, which will persist until the next significant disturbance. The change in community structure and the diversity of species are influenced by abiotic factors including soil quality, water availability, and climate.

Rabbit ears can be either shorter floppy where short ears or dominant over floppy ears there are 653 individuals in a population of 104 rabbits have floppy years and 549 have short ears find the frequency of dominant and recessive alleles and the frequency of individuals with dominant heterozygous and recessive genotypes
Answer:
frequency of dominant and recessive alleles - 0.6, 0.4
frequency of individuals with dominant, heterozygous and recessive genotypes - 0.36, 0.48, 0.16
Explanation:
Given -
Short ears (S) is dominant over floppy ears.
Total population of rabbits [tex]= 653[/tex]
Population of rabbits with floppy ears [tex]= 104[/tex]
Population of rabbits with short ears [tex]= 549[/tex]
Frequency of rabbits with floppy ears is equal to
[tex]\frac{104}{653} \\= 0.159[/tex]
Thus as per Hardy weinberg's equation, frequency of recessive phenotype is represented by [tex]q^2\\[/tex]
Thus,
[tex]q^2 = 0.159 =0.16\\q = \sqrt{0.16} \\q = 0.4[/tex]
Thus,
[tex]p = 1-q\\p = 1-0.4\\p= 0.6[/tex]
Frequency of rabbits with short ears only
[tex]= p^ 2 \\= 0.6^2\\= 0.36\\[/tex]
Frequency of heterozygous rabbit (Ss)
[tex]p^2 + q^2 + 2pq = 1\\0.16 + 0.36 + 2pq = 1\\2pq = 1 - 0.36-0.16\\2pq = 0.48[/tex]
The frequency of the dominant allele is 0.81, the frequency of the recessive allele is 0.19, the frequency of individuals with dominant heterozygous genotype is 0.3098, and the frequency of individuals with recessive genotype is 0.0361.
Explanation:The question asks for the frequency of the dominant and recessive alleles, as well as the frequency of individuals with dominant heterozygous and recessive genotypes. To calculate these frequencies, we need to know the number of individuals with each genotype.
Given that there are 653 individuals with floppy ears and 549 individuals with short ears, we can determine the frequencies as follows:
The frequency of the dominant allele (p) can be calculated as the square root of the frequency of individuals with floppy ears. In this case, p = √(653/104) = 0.81.The frequency of the recessive allele (q) can be calculated as 1 - p. In this case, q = 1 - 0.81 = 0.19.The frequency of individuals with dominant heterozygous (Hh) genotype can be calculated as 2 * p * q. In this case, Hh = 2 * 0.81 * 0.19 = 0.3098.The frequency of individuals with recessive (hh) genotype can be calculated as q². In this case, hh = 0.19² = 0.0361.Therefore, the frequency of the dominant allele is 0.81, the frequency of the recessive allele is 0.19, the frequency of individuals with dominant heterozygous genotype is 0.3098, and the frequency of individuals with recessive genotype is 0.0361.

B. It does nothing to protect scientists working in Antarctica.
C. It lacks references to mineral resources.
D. It does nothing to protect the atmosphere over Antarctica,
Answer:
The correct option is D) It does nothing to protect the atmosphere over Antarctica.
Explanation:
On December 1, 1959, the Antarctic Treaty was signed in Washington. According to this treaty, Antarctica was to be used for peaceful purposes. This treaty regulates international relations with the Antarctica region. Freedom to different scientists for research in this area was given through this treaty.
However, the treaty did not discuss anything related to the protection of the atmosphere around Antarctica. Hence, option D can be considered to be a limitation of the Antarctic Treaty System.

Explanation:
Answer:
Option B A much warmer climate than what we are currently experiencing.
24 hours of daylight, as experienced in the summers at both poles
currently
Explanation:
The change in the earth's orbit pathway affects the change in the climatic conditions of the earth. For example, the earth, when it is closer to the sun, results in a warmer climate.
However, the earth, when the axis is a little away from the sun, results in a slight decrease in the temperature of the earth.
Thus, when the orbit is highly elliptical, the amount of isolation received at perihelion would be on the order of 20 to 30 percent greater than at aphelion resulting in a warmer climate.

1) How is DNA condensed to form a chromosome?
2) What is the difference of mechanism genes and the DNA
segments between them?
3) What is the difference between a gene expression and the
genetic code?
(Will give brainliest if answered correctly)
Answer:
1) DNA is wrapped around histone proteins to form chromatin
2) The genes are the functional units, the segments between them are used for regulation
3) The genetic code is the language used, gene expression is how the cell uses the information, the activity of the genes.
Explanation:
1) DNA forms a DNA/protein complex called chromatin. It does this by wrapping around histone proteins. These histone proteins are usually present in the form of a nucleosome, which is a unit containing 2 copies of 4 histones (H2A, H2B, H3 and H4). The chromatin fibre at its most compact forms tightly coiled structures called chromosomes. These structures are only present during cell division. When the cell is in interphase (i.e. not dividing), the chromatin is not as tightly condensed, and instead the chromatin is more relaxed to allow the genes within to be expressed.
2) Genes are the functional units that the cell uses to make RNA and protein. The genes are first transcribed into RNA, which is processed and then translated into a polypeptide chain, which forms a complete protein that performs activities in the cell/tissue/organism. However, the whole genome does not form genes, there are regions that do not correspond to a gene. These regions are called "non-coding DNA" or sometimes even "junk DNA". However, that does not mean that these regions do not have important roles. The role of this DNA is usually in regulating the activity of the nearby genes. This DNA might contain important regulatory sequences such as promoters/enhancers/silencers that control how the gene is used by the cell, by for example, recruiting transcription factors or silencing proteins.
3) The genetic code is the language used by the cell. It explains how the cell can transcribe the information in the DNA, to RNA, process the RNA, and then translate the RNA into a polypeptide, and eventually a mature protein. In contrast, gene expression represents how the cell actually uses this information. Not all the genes are transcribed at the same time, instead, the activity of genes is carefully controlled to produce appropriate gene expression patterns, allowing the cell to properly perform its functions. Gene expression is hugely different between cells in an organism, for example the gene expression patterns of a muscle cell will be hugely different to that of a blood cell.

Answer:
Intraspecific competition
Explanation:
Intraspecific competition can be described as a competition which arises between organisms of the same species. The organisms might compete with one another due to the limited resources present such as water, food, shelter, mating partner etc. For example, two male birds of the same species competing for mates in the same area.
On the contrary, interspecific competition can be described as the competition which arises between organisms of different species.
an asteroid can have a moon if the
Final answer:
Asteroids can have moons if their gravity is strong enough to capture smaller objects into orbit. This has been observed with asteroids like Ida and its moon Dactyl, and is evidenced by Mars's moons, Phobos and Deimos, which are probably captured asteroids.
Explanation:
Can an Asteroid Have a Moon?
An asteroid can indeed have a moon, as we've learned from observations of asteroids such as Ida and its moon, Dactyl. When the Galileo spacecraft flew by Ida, it discovered Dactyl, a moon orbiting the asteroid. Dactyl's presence allowed scientists to measure Ida's mass and density using Kepler's laws. This is significant because, typically, an asteroid can have a moon if the asteroid's gravity is sufficient to capture a smaller object into its orbit, either as a result of an impact event or through a capture process.
For example, Phobos and Deimos, the two moons of Mars, are believed to be captured asteroids. Larger bodies in the solar system, like Jupiter and Saturn, have also probably captured smaller asteroids to form some of their moons. This demonstrates that asteroid moons are an important part of our understanding of the formation and evolution of our solar system.
The possibility of an asteroid having a moon adds valuable data to our knowledge of asteroid masses and densities, which in turn informs us about the conditions in the early solar system and the processes involved in planetary formation. It's fascinating to think of how the dynamics of smaller celestial bodies contribute to the intricate dance of our cosmic neighborhood.

Because water has a higher specific heat then land, it what?
Answer:
Though water has higher specific heat than land it can absorbs and releases heat slower than land.
Explanation:
The specific heat of the water is higher than land, that's why it has the tendency to absorb and release the heat slower as compared to the land. It also takes more heat to increase the temperature for one gram of water by one degree than it also does to increase the temperature of the land. similarly the heat absorbed by the ocean is almost spread in the greater volume as the ocean is a transparent body.
