Answer:
Somatic cells are diploid, meaning that they have two copies of the human genome.
Explanation:
Somatic cells are any of the cells found in the body which are not gametes or germ cells. They are diploid in that they contain two sets of chromosomes, one inherited from each parent.
A germ cell is a cell containing half the number of chromosomes (are haploid) and able to fuse with one from the opposite sex to form a new individual. They undergo the process of mieosis to become haploid cells.
Stem cells are undifferentiated or unspecialized cells with self-renewal capacity. They can divide through mitosis limitlessly to replenish other cell types of multicellular organisms throughout their life. They contain two sets of chromosomes (are diploid) one from each parent. They of two types: embryonic and adult somatic stem cells.
True: Somatic cells are diploid, meaning that they have two copies of the human genome.
False: Somatic cells are haploid, meaning that they have one copy of the human genome.
False: Sperm and egg cells are diploid, meaning that they have two copies of the human genome.
False: Stem cells are haploid, meaning that they have one copy of the human genome.

Scientists have a theory about the relationship between climate and biodiversity. Which best describes this theory?
Options are not given in the question, so the complete question is as follows:
Scientists have a theory about the relationship between climate and biodiversity. Which best describes this theory?
A) Warmer climates promote higher biodiversity, allowing plants to grow year-round. This supports more organisms that rely on plants.
B) Colder climates promote higher biodiversity, reducing the competition among organisms for food. This supports stronger organisms that live longer.
C) Warmer climates promote higher biodiversity because they tend to receive more rainfall. This provides a source of water for more organisms.
D) Colder climates promote higher biodiversity because they are usually larger in size. This provides space for more organisms
Answer:
C)
Explanation:
Climate and biodiversity have a close relationship with each other.
The theory that best describes this relationship is that "Warmer climates are responsible for higher amount of rainfall and give rise to higher biodiversity and also provide a source of water for existing organisms."
Hence, the correct option is "C".

Is it possible that photosynthesis is occurring in a leaf that is not floating? Explain this and support your answer with your data.
Answer:
Yes
Explanation: The oxygen that is produced is what is making the leaf float. O2 is the result of the photosynthesis process.
Air-filled tissues in various parts of the plant provide the buoyancy that allows them to float.
Leaves have air in the spaces between cells, which helps them collect CO2 gas from their environment to use in photosynthesis.To get to the spongy mesophyll cells inside the leaf, gases diffuse through small pores called stomata . They also open or close to control the loss of water from leaf by the process of transpiration .What is photosynthesis?Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas as raw materials. Chlorophyll is a substance in all green plants, especially in the leaves.It provides oxygen in atmosphere for all living organisms. It maintains the balanced level of oxygen and carbon dioxide ecosystem.To know more about ecosystem here

Biology shows us the fossil record and comparative anatomies. Chemistry shows us that organic molecules can come from inorganic matter. Geology shows us that organisms that used to live together are found on separate continents due to continental drift.
Which fields of science provide evidence for evolution?
biology only
biology and chemistry only
biology and geology only
biology, chemistry, and geology
Answer:
biology, chemistry, and geology
Explanation:
Biology, chemistry, and geology are the fields of science that provide evidence for evolution, hence option D is correct.
What is the evidence of evolution?The uniformity of the fossil sequence from ancient to modern is possibly the strongest fossil evidence for evolution.
Fossils are a reflection of evolution and geological change due to their global distribution of organisms and distinctive traits of island species. The existence of species that are related to modern species but are now extinct is documented through fossils.
It is the series of slow, irreversible changes that occurred in early creatures over millions of years to give rise to new species we know today. Errors in DNA copying and sexual reproduction are mostly to blame for variations that led to the emergence of new species.
Therefore, biology, chemistry, and geology are the fields of science that provide evidence for evolution.

Protein kinases are enzymes that act on other enzymes by adding phosphates groups. When the enzyme is phosphorylated, it changes its activity (it becomes more or less active, depending on the enzyme). This regulatory mechanism of enzymatic activity is called
Answer:
The regulatory mechanism of enzymatic activity is known as Phosphorylation
Explanation:
Phosphorylation usually results in a functional change of the target protein (substrate) by changing enzyme activity, cellular location, or association with other proteins.
Answer:
The feedback inhibition regulatory mechanism. They do this by causing phosphorylation of the other enzyme.
Explanation:
There are two ways by which enzymes can be controlled or regulated. This includes
1. Controlling the synthesis of the enzyme (this relates to a genetic control)
2. Controlling the activity of the enzyme (feedback inhibition).
In this example here, the protein kinases act on other enzymes by adding phosphates groups bringing about phosphorylation and controlling or regulating the activity of these enzymes. Thus, this type of regularly is the feedback inhibition regulatory mechanism.

Nucleotide bases of the DNA contain the instructions on how to control cells.
How does DNA control cells?The hundreds of distinct types of proteins that are produced by cells are coded by the nucleotide sequences that make up DNA. These proteins control and regulate cell development, division, communication with other cells, and the majority of other cellular functions. This is the reason why nucleotide sequences found in DNA are referred to as carrying or storing information.Protein synthesis:
The sequences must first be "decoded," and the protein must then be translated. It is known as protein synthesis.
Transcription (first stage of protein synthesis): The process of copying information from a strand of DNA into a messenger RNA (mRNA) molecule is called transcription. DNA preserves genetic material as a reference or template safely and permanently in the cell nuclei.Translation (second stage of protein synthesis): The process of translation converts the information carried by messenger RNA from DNA into a string of amino acids. Essentially, it involves translating a code (nucleotide sequence) into another code (amino acid sequence).Learn more about protein synthesis here:

what causes competition in an eco system?
Answer:
Increasing members in the higher trophic level causes competition in an ecosystem.
Explanation:
For example, if there is a shortage of producers, the primary consumers will face a higher competition for food. Thus, many will die. Death of primary consumers will increase the competition in secondary consumers as they are left with less food options. This will go on till the tertiary consumer, and the competition will continue until each trophic level is balanced.
Answer: Competition in ecosystems.
Explanation:
Competition will occur between organisms in an ecosystem when their niches overlap, they both try to use the same resource and the resource is in short supply. Animals compete for food, water and space to live.

In anaphase I of meiosis, ______ separate while in anaphase of mitosis ______ separate microtubules, microfilaments spindle fiber, nuclear envelope nuclear envelope, spindle fiber sister chromatids, homologous chromosomes homologous chromosomes, sister chromatids
Answer:
In anaphase I of meiosis, the homologous chromosomes separate while in anaphase of mitosis the sister chromatids separate
Explanation:
During meiosis I, the chromosomes are duplicated (i.e., they are bivalents). Moreover, in Anaphase I, the sister chromatids continue attached to each other, while homologous bivalent chromosomes already condensed in prophase I separate.
The spindle fibers are a type of microtubule that helps to separate the genetic material during cell division.
The microfilaments are structures formed by actin subunits and they form a contractile ring during cytokinesis, or cytoplasm division.
