Answer:
O (2) an increase in pulse rate
An increase in heart rate will most likely result in an increase in pulse rate. So, the correct answer is (B).
What is Heart?Heart is a fist shaped organ which pumps blood throughout your body present in the centre of the chest tilted slightly towards the left. It is the primary organ of the circulatory system which pump blood around the body as the heart beats. The blood sends oxygen and nutrients to all parts of the body and carries away unwanted carbon dioxide and waste products from there.
Heart has four chambers (lobes) made up of muscles- two on the left side and two on the right made up of three layers of tissue -epicardium, myocardium and endocardium. These layers are surrounded by the pericardium which a thin outer lining protecting the heart.
It circulates abut 5-8 liters of blood. Heart, blood and blood vessels together make the cardiovascular system. Blood is pumped around your body through a network of blood vessels- Arteries, Capillaries and veins. Heart has four valves which act like gates which keep the blood moving in the right direction.
Thus, an increase in heart rate will most likely result in an increase in pulse rate. So, the correct answer is (B).

3. The presence of Malaria in many countries has been eradicated and even in parts of Africa, the incidence of Malaria has been reduced substantially. Without endemic malaria from Africa, the sickle cell mutation is purely disadvantageous. What do you think will happen to the percentage of people carrying the Sickle Cell gene over time under the pressures of natural selection
Answer:
The percentage of people carrying sickle cell gene increases.
Explanation:
People carrying the Sickle Cell gene have low chance of Malaria because the sickle cell enables the body to detoxify abnormal red blood cells from the body. When the malarial parasite attacks on the cells of the body, the molecular machinery for cleaning up the waste is already present in the body. Those places where malaria is common, the people having sickle cell because the sickle cell show resistance against malarial disease.

Algae provides more energy to the Box Turtle population.
If you see the bottom of the chain, Algae, whether the turtles eat it or not, also provides energy/food/resource for other forms of energy the turtles can consume, it's the base of the chain.
The answer is not aquatic insects because they do not supply as energy to as many sources as algae.

Use a Punnett square diagram to show why, for each pregnancy, the chances of giving birth to either a boy or a girl are 50-50. Explain the results shown in your diagram.
Answer:
Because the offspring of a male and female are always going to be xx, xx, xy, or xy.
Explanation:
Remember that men have different reproductive chromesomes than women. Women have 2 x chromesomes(xx) while men have 1 x and 1 y(xy). These are given down to their offspring.
So we can write the this out in a punnet square as(link down below).
After you see the visual, you will find that the genotypes are xx, xx, xy, xy.
As I said above, women have sex chromesomes xx, while men have sex chromesomes xy. When you match the genotypes on the punnet square with the ones we know from men and women, we find that two of them match with men and two match with female.
So with this, we can conclude that 2/4 of offspring will always be male and 2 will be female. And as you well know 2/4 is 1/2 which is 50%.
which process is needed for evolution to occur? PLEASSE HELPPP THIS IS A BIG GRADE
Answer: D. Genetic mutation
Explanation:
For evolution to occur, there must be a genetic mutation in the genome of an organism such that a new allele is formed.
If this mutation occurred in the sperm and/or the ovum, the mutation will then be passed on through reproduction to the next generation. This leads to more of the subsequent generations having that mutation thereby leading to evolution.
In the liver, excess amino acids are broken down into ____________ and rapidly combine with ____________ to produce urea, which is much less toxic to cells.
Answer:
In the liver, excess amino acids are broken down into ammonia and rapidly combine with carbon dioxide to produce urea, which is much less toxic to cells.
Explanation:
The correct answer to the given quested about Urea Cycle is Ammonia and Carbon dioxide respectively and the complete statement will be "In the liver, excess amino acids are broken down into Ammonia and rapidly combine with Carbon Dioxide to produce urea, which is much less toxic to cells."
What do you mean by Urea Cycle?The urea cycle, commonly referred to as the ornithine cycle, is a series of metabolic processes that converts ammonia into urea (NH2)2CO (NH3).Highly poisonous ammonia is transformed into urea by rapidly combining with carbon dioxide via the urea cycle for elimination. Five years before the TCA cycle was found, this cycle was the first to be identified as a metabolic process. Later, Ratner and Cohen provided a more thorough explanation of this cycle.Thus we can conclude that in the liver, excess amino acids are broken down into Ammonia which is highly toxic to cells and that ammonia rapidly combine with Carbon Dioxide to produce urea, which is much less toxic to cells.

The smaller a population of organisms of a particular species, the
A.
more likely one of the organisms is to adapt to a changing environment
B.
more likely a mutation is to arise
C.
less likely the species will be able to survive in a changing environment
D.
less likely natural selection is to affect the population
Answer:
The correct answer is - D. less likely natural selection is to affect the population
Explanation:
The larger population of a species tends to produce more mutant individuals per generation than a smaller population per generation. In a larger population, it assists to get more genotypes and gets optimal genotypes quicker than smaller populations.
In larger populations, the process of natural selection is more effective and for the smaller population Second, natural selection is less likely to affect the population which leads to less genetic diversity or change in order to survive due to stochastic sampling error as some allele loss in random selection.
