What are cell organelles?An organelle is a type of subcellular structure that, much like an organ in the body, is responsible for performing one or more specialized tasks within the context of the cell. The nucleus, which are responsible for storing genetic information, the mitochondria, which are responsible for producing chemical energy, and the ribosomes, which are responsible for assembling proteins, are some of the more essential organelles found in cells.
The nucleolus, the nucleus, the ribosome, the vesicle, the rough endoplasmic reticulum, the Golgi apparatus, the cytoskeleton, the smooth endoplasmic reticulum, the mitochondria, the vacuole, the cytosol, the lysosome, and the centriole are the major organelles and structures found within the cytoplasm.

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.

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.

How are the daughter cells produced by meiosis
different from those produced by mitosis?
Answer:
In mitosis, the daughter cells have the same number of chromosomes as the parent cell. But, in while meiosis, the daughter cells have half the number of chromosomes as the parent.
The daughter cells produced by mitosis are identical, whereas the daughter cells produced by meiosis are different because crossing over has occurred.
Explanation:
In mitosis, the cells of the daughter are as many chromosomes as the cell of the parent, and the cells of the daughter in meiosis are as many as the chromosome of the parent. Mitosis-generated daughter cells are similar, while meiosis-generated daughter cells are special as they cross.

Iodine-131, a beta emitter, is one such product of nuclear fission, extremely dangerous because it is typically produced in huge quantities and because it is incorporated in the human body in the thyroid gland. The half-life of 1311 is 8.04 days. What fraction (expressed as a decimal number) of the 1311 produced in a nuclear accident would remain after 60.0 days?
Answer:
0.00568
Explanation:
Recall that the fraction of radioactive material left after a time (t) is obtained from the formula;
N/No = (1/2)^t/t1/2
Where;
N= mass of radioactive material left after a time t
No= mass of radioactive material initially present
t= time taken for N mass of radioactive substance to remain = 60.0 days
t1/2= half-life of the radioactive substance= 8.04 days
Note that the required fraction is N/No, hence;
N/No= (1/2)^60.0/8.04
N/No= (1/2)^7.46
N/No = 0.00568
Instructions on how to control your cells are contained in what part of the DNA?
A. Pentose Sugar
B. Phosphate group
Hydrogen bonds
D. Nucleotide bases
Answer:
D. Nucleotide bases
Explanation:
Hope it helps.
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:

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.

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.
