Explanation:
The presence of cilia, flagella and pseudopods improve the chances of survival of a protist by increasing the likelihood of obtaining nutrients. Thus, the correct option is A.
What is locomotion?
Locomotion is the basic act or ability of something to transport or move itself from one place to another. Many protist species have the presence of some type of locomotory organelles on their body which are easily visible under a light microscope. A protists can move by gliding or floating, and by use of organelles such as flagella or cilia.
Protists use these locomotory organelles to find food, a mate, a suitable habitat or to survive and escape form the predators. Types of Movements involved in locomotion include axial and appendicular.
Therefore, the correct option is A.

How many alleles are typically found for mitochondrial genes?
1. 8
2. 1
3. 4
4. 2
Answer:
The answer is 2.1
Answer:
two alleles
Explanation: because This dynamic aspect of mitochondrial transmission from cell to cell is termed mitotic segregation. In Mendelian genetics, a person's nuclear DNA can contain, at most, only two alleles for any particular autosomal gene, one paternally derived (e.g., allele “A”) and the other maternally derived (e.g., allele “B”).

A class is debating the advantages and disadvantages of different types of reproduction. One student argues that organisms that reproduce asexually, like bacteria, have no advantage over organisms that reproduce sexually.
Which of the following choices below represents an argument for the advantages of asexual reproduction?
A. Organisms that reproduce asexually are likely to find a mate at a faster rate than sexually reproducing organisms, which allows them to reproduce faster.
B. Organisms that reproduce asexually are more diverse and are more likely to pass on key genes for survival to future generations, which aids in maintaining beneficial genes for survival in the gene pool
C. Organisms that reproduce asexually gain variation through processes like crossing over, which allows survival in instances of ecological change
D. Organisms that reproduce asexually create a large amount of offspring in a short period of time in order to maintain their population
Answer: D. Organisms that reproduce asexually create a large amount of offspring in a short period of time in order to maintain their population.
Explanation:
When an organism is able to reproduce asexually as opposed to sexually, it means that they do not require a mate to make offspring. Offspring of such organisms will therefore receive all their genes from one source.
Such organisms are able to reproduce very fast when they are presented with adequate conditions especially because they do not need another organism to do so. They will neither have to waste much energy nor have to go through the whole sexual process so they will be able to produce lots of offspring.
Animals are known to have offspring through asexual and/or sexual reproduction. The choices that has an argument for the advantages of asexual reproduction is that Organisms that reproduce asexually create a large amount of offspring in a short period of time in order to maintain their population.
Asexual reproduction is simply known as a type of reproduction where offspring are genetically identical to the parent.The offspring are regarded as clones that derives its root from the original parent.
A single individual can have offspring asexually and also in large numbers quickly.

In the biosphere, _________________ is an important element in ATP (Adenosine triphosphate) and DNA (Deoxyribonucleic acid).
A. Phosphorus
B. Phosphate
C. Photosynthesis
D. Photons
In the biosphere, phosphorus is an important element in ATP (Adenosine triphosphate) and DNA (Deoxyribonucleic Acid), which is in Option A, as phosphorus is a crucial element in the biosphere as it is a component of both ATP (Adenosine triphosphate) and DNA (Deoxyribonucleic Acid).
What is phosphorus?Phosphorus is essential for the formation of the backbone of the DNA molecule, where it links the sugar and nitrogenous base components of the nucleotides. The phosphate group of each nucleotide forms a covalent bond with the sugar molecule of the adjacent nucleotide, forming a long, stable chain of nucleotides that make up the DNA molecule. The DNA molecule is responsible for transmitting genetic information from parent to offspring and serves as a blueprint for the development and function of living organisms.
Hence, in the biosphere, phosphorus is an important element in ATP (adenosine triphosphate) and DNA (deoxyribonucleic acid), which are in Option A.
