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.
Hope this helped!

Which is NOT a benefit of xenophyophores in a habitat?
1 They maintain benthic biodiversity.
2 They increase populations of isopods, mollusks, and crustaceans.
3 They churn up sediments that build up on the ocean floor.
4 They convert salt and iron into energy and nutrients.
The correct answer is 4. They convert salt and iron into energy and nutrients.
Explanation
Xenophiophores are large single-celled organisms generally found deep in the deep sea. They are characterized by being very delicate organisms, which makes it difficult for scientists who intend to study them since they are easily damaged by manipulation. However, in the studies that have been carried out on these organisms, it has been found that they are irreplaceable agents in the sediment deposition process and the maintenance of the biological diversity of benthic organisms. Also, it has been shown that in the areas where these organisms are found there are three to four times more benthic crustaceans, echinoderms, and mollusks than the equivalent areas not inhabited by these organisms. On the other hand, none of these studies has proven that They convert salt and iron into energy and nutrients. Therefore, the correct answer is 4. They convert salt and iron into energy and nutrients.

Which of the following factors decrease biodiversity? (Choose all that apply)
a. habitat destruction
b. unpredictable precipitation
c. warm temperatures
d. freezing temperatures
Answer:
habitat destruction, unpredictable precipitation, and freeing temperatures.
Explanation:
i took the quiz
The destruction of the habitat, unpredictable precipitation, and freezing temperatures decreases biodiversity. Thus, options a, b, and d are correct.
What is biodiversity?Biodiversity is the variety of life that sustains on earth and lives in a particular habitat. The biodiversity can be measured based on the ecosystem, species, and genetics. It comprises the ecological and evolutionary process.
The destruction of the habitat of a species can lead to a decrease in biodiversity as it affects the ecosystem and the ecological pyramid as a whole and will affect the population of the species.
The unpredictable precipitation can affect the species and the habitat as it may lead to floods that will destroy the habitat hence resulting in the loss of species.
Similarly, the decrease in temperature will affect many species as they will not be able to cope with low temperature resulting in their death.
Therefore, the unpredictable precipitation, freezing temperature, and destruction of habitat lead to a decrease in biodiversity.

Explanation:
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 humans, dimples are dominant to no dimples and freckles are dominant to no freckles. A man with
no dimples or freckles mates with a woman who is heterozygous for both traits. Determine the
percentage of their offspring that will have the same genotype as their mother. Also determine the
percentage of their offspring that will have the same phenotype as their father.
Answer:
I'm being honest the answer are in the pdf pls don't report me its not a scam
Explanation:
The correct answer is 25% of their offspring will have the same genotype as their mother.
25% of their offspring will have the same phenotype as their father.
What is genotype?The term genotype refers to an organism's whole complement of genes; in other words, it describes its genetic composition. In a more restricted meaning, the phrase can refer to the alleles, or alternative forms of a gene, that an organism carries.
what is phenotype?A phenotype is just an observable trait. Pheno means observe and is derived from the same root as "phenomenon." As a result, it's an observable sort of organism that can refer to anything from a common characteristic like height or hair color to the presence or absence of a disease.

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.

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.

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.
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%.
