5. Besides being part of the composition of bone, why else do mammals need calcium?
Answers
Answer:
It's important for the contracting muscle
Explanation:
Besides being part of the composition of bones, calcium is needed by mammals for the following processes:
Formation of skeletons and teeth.Muscle contraction.Regulation of normal heart rate and nerve functions. Blood clotting. What is Calcium in living organisms?Calcium in living organisms may be defined as an important nutrient that all living organisms require, including humans in order to develop various organs like teeth and bones as well as for metabolic processes.
Apart from being part of the composition of bones, calcium is also required for the proper development of teeth and skeletons. The movement of calcium ions plays an essential role in the contraction of muscles.
The influx of calcium ions into the cells of the heart significantly enhances the heart rate of an individual in the range of 1.6 to 14.10 mm.
It also plays a critical role in blood clotting.
Therefore, it is well described above.

Which of the following facts about rain forest illustrates the negative effect of their destruction on the environment?
Answers
The release of carbon dioxide during the burning of the rainforest adds to the greenhouse effects.
What is greenhouse effect?The greenhouse effect occurs when energy from a planet's host star passes through its atmosphere and heats its surface, but greenhouse gases in the atmosphere prevent some of the heat from returning directly to space, resulting in a warmer planet.
The greenhouse effect describes how "greenhouse gases" trap heat near the Earth's surface. These heat-trapping gases act like a blanket wrapped around Earth, keeping it warmer than it would be without them.

Case Study
1) Tianna was riding her horse on a warm sunny day (101 degrees Fahrenheit). She had overdressed for the day, not knowing it was going to be this hot. She had already sweated out 1 Liter of fluids and her respiratory rate was increasing (currently at 23 breaths per minute while sitting). She was also feeling dizzy and not well.
Answers
To help the lower temperature of Tianna on a hot day, the hypothalamus, a part of the endocrine system of the body induces the production of the thyroid hormone, thyroxine, that induces sweating in order to lower the body temperature.
What is thermoregulation?
The process through which the body controls its internal temperature is known as thermoregulation. Extreme discomfort and even death could result from having a body temperature that is excessively cold or high.
The hypothalamus helps keep the body's internal functions in balance by producing hormones that help to regulate body temperature.
Sweating is one of the main ways your body regulates temperature when exposed to hot temperatures. The evaporation of sweat assists in cooling the skin. Additionally, the blood arteries feeding the skin widen, allowing warm blood to travel to the skin's surface. This aids in cooling the body's core.

What are the features of polymerase chain reaction?The polymerase chain reaction is a method widely used to rapidly make millions to billions of copies of a specific DNA sample.
PCR is based on three simple steps required for any DNA synthesis reaction: (1) denaturation of the template into single strands; (2) annealing of primers to each original strand for new strand synthesis; and (3) extension of the new DNA strands from the primers.
As PCR progresses, the DNA generated is itself used as a template for replication, setting in motion a chain reaction in which the original DNA template is exponentially amplified.

How do the layers of the atmosphere help to understand better the dynamics of the atmosphere and its relationship to the hydrosphere and lithosphere?
Answers
There are various layers that make up the atmosphere, and each has distinct properties and functions. Both weather generation and energy transmission take place in the troposphere, which is closest to the Earth's surface.
The stratosphere shields the Earth from damaging UV radiation along with the ozone layer. Most auroras happen in the mesosphere, where meteors burn up. Modern technology is dependent on the thermosphere, where the majority of the Earth's satellites orbit and where communication signals are sent.
The dynamics of the atmosphere and its interactions with the hydrosphere and lithosphere are better understood thanks to these layers. Foreseeing and minimising environmental problems like climate change and preserving our world, it is essential to understand the significance of each layer.

What do you learn from the adaptation of animals according to the environment?Sometimes, in response to a prolonged change in environmental characteristic, an animal's physiology adjusts to accommodate the change in its environment, and in doing so, its tolerance range shifts. This shift in tolerance range is called acclimation.A kangaroo rat is small animal that is found in the deserts of the southern and western U.S.. They are intelligent mammals and are highly adapted to their environment.The kangaroo rats does not drink water and does not need water at all. They preserve water. They have well adapted themselves to the life of a desert. They can extract moisture form their seed diet. They have an excellent sense of hearing and can hear the approaching owl from mile away.The kangaroo rats have thick oily coats and they do not sweat though they live in the desert.

Calico cats have patches of black and orange fur X inactivation X-linked Color blindness is more common in men "Heterozygotes" can express the recessive phenotype Hemophilia Rett syndrome is not always fatal in females Barr bodies
Answers
Answer:
X chromosome inactivation:
- Calico cats have patches of black and orange fur
- "Heterozygotes" can express the recessive phenotype
- Rett syndrome is not always fatal in females
- Barr bodies
X linked traits:
- Color blindness is more common in men
- Hemophilia
Explanation:
X chromosome inactivation refers to the mechanism in which one X chromosome is randomly inactivated during early embryonic development in female mammals. The inactivated (silenced) X chromosome is condensed into a structure called Barr body. In cats, the gene encoding for the orange/non-orange fur coloring is X-linked, thereby X inactivation explains why most calico cats (i.e., those cats that have a color pattern with orange and black spots) are female. Moreover, Rett syndrome is a neurodevelopmental disorder caused by a mutation in the X-linked MECP2 gene, and therefore this disorder is much more serious in males. On the other hand, color blindness is more common in men because males have only one X chromosome. In the same way, hemophilia, which is a disorder caused due by a mutation in one gene required for synthesizing one clotting factor, is more common in males than in females because the gene responsible for this disorder is located on the X chromosome.

Calculate the equilibrium genotype frequencies from a population with allele frequencies p=.25 and q=.75
Answers
There are 6.25% homozygous dominant people (AA), 37.5% heterozygous people (Aa), and 56.25% homozygous recessive people (aa).
How to determine equilibrium genotype frequencies?In a population with two alleles, p and q, the frequency of p and q must add up to 1, or 100%. In this case, p = 0.25 and q = 0.75.
Using the Hardy-Weinberg equation, we can calculate the expected frequencies of the three possible genotypes: AA, Aa, and aa. The equation is:
p² + 2pq + q² = 1
where p² represents the frequency of the AA genotype, 2pq represents the frequency of the Aa genotype, and q² represents the frequency of the aa genotype.
Substituting the given values of p and q:
(0.25)² + 2(0.25)(0.75) + (0.75)² = 1
0.0625 + 0.375 + 0.5625 = 1
Therefore, the expected frequencies of the three genotypes are:
AA = p² = (0.25)² = 0.0625
Aa = 2pq = 2(0.25)(0.75) = 0.375
aa = q² = (0.75)² = 0.5625
So in this population, we would expect to see 6.25% homozygous dominant individuals (AA), 37.5% heterozygous individuals (Aa), and 56.25% homozygous recessive individuals (aa).

The question is asking how to find if temperature impacts oxygen levels. The correct answer would be B.
To determine if the temperature impacts oxygen you would want to alter the temperature as an independent or control variable and see how that impacts oxygen in the water which would be a dependent or response variable.
