How does the number of genes in human cells compare with the numbers in other species?
Answer:
While the number of genes in an organism's DNA (red bars) varies from species to species (numbers at right), it is not always proportional to genome size (blue bars, in millions of base pairs). Note how many genes a fruit fly can squeeze out of its relatively small genome.
What is a gene?
A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins.
In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.Comparative genomics also provides a powerful tool for studying evolutionary changes among organisms, helping to identify genes that are conserved or common among species, as well as genes that give each organism its unique characteristics.While the number of genes in an organism's DNA varies from species to species, it is not always proportional to genome size.Learn more:

If chemical signals in the cytoplasm control the progression of a cell to the M phase of the cell cycle, then fusion of a cell in G1 with a cell in early M phase would most likely result in the Group of answer choices replication of chromosomes only in the G1 cell transfer of organelles from the G1 cell to the cell in the M phase condensation of chromatin in preparation of nuclear division in both cells exiting of both cells from the cell cycle and into the G0 phase
Answer:
condensation of chromatin in preparation of nuclear division in both cells
Explanation:
Mitosis, as a type of cell division, is divided into Interphase and the Mitotic phase. The interphase further comprises of G1, S and G2 phases while the mitotic phase consists of mitosis and cytokinesis.
Mitosis is a form of nuclear division i.e. separation of genetic material (chromosome). According to this question, chemical signals in the cytoplasm control the progression of a cell to the M phase of the cell cycle.
Since what occurs in the M phase of the cell cycle is nuclear division, then fusion of a cell in G1 with a cell in early M phase would most likely result in "the CONDENSATION OF CHROMATIN in preparation of NUCLEAR DIVISION in both cells".

more likely it is that some individuals will?
a) evolve.
b) migrate.
c) survive.
d) mutate.
Answer:
b migrate
Explanation:
sorry if im wrong
The more genetic variation a population has, the more likely it is that some individuals will migrate.
what is population ?A discrete accumulation identifiable characteristics such as people, animals with the objective of analysis and data collection is called a population.
A population consists of a same group of species who reside in a particular geographical place with their reproductive capacity to interbreed.
In a population Not all individuals are able to survive and reproduce due to genetic variations in them, a local population is restricted to a smaller area or can occupy a larger area, making up for the entire species.
when individuals in local populations spread between other local populations called as metapopulation.

You are looking under a microscope at a dividing cell. You notice
the chromatin has just condensed into chromosomes, the nuclear
membrane has started to break down and the spindle has started
forming. What phase is the cell in?
Answer:
Prophase.
Explanation:
Prophase is the phase of mitosis in which chromatin condenses into chromosomes, the nuclear membrane is started to break down and the forming of spindle has started . Prophase is the first stage of mitosis which occurs after G2 portion of interphase. After prophase, metaphase, anaphase, and telophase occurs that completes the cell division process and the one parent cell divides into two daughter cells.

How many cells do you start with for mitosis?
Define these types of relationships (symbiosis).
a. mutualism -
b. commensalism-
c. parasitism -
d. predator/prey -
e. competition -
Answer:
mutualism -Both species benefit
commensalism- One species lives with, on, or in another species (the host). The host species neither benefits nor is harmed from the relationship. The species that lives on the host is benefited.
parasitism - One species (the parasite) lives with, on, or in a host species, at the expense of the host species. Unlike in predation, the host is not immediately killed by the parasite, though it may sicken and die over time.
predator/prey -One species (the predator) hunts and kills another species (the prey)
competition -The struggle among organisms for the same limited resources in an ecosystem

Conduct online research and describe how oil and gas are formed in the ocean bed and how they are tapped for human use.
Answer:
oil and gas are formed in tje ocean bed and how they are tapped for human use is below:
Explanation:
Gas and oil form in the sea over a period of millions of years, as the remains of animals and plants sink to the ocean floor. Combined with particles flushed from the land, they are buried and compressed into layers of sediment several kilometres thick on the ocean floor
An animal that is endothermic and homoeothermic A. uses metabolic energy to regulate its body temperature and maintains a relatively constant body temperature B. has its body temperature determined primarily by the environment, but maintains a relatively constant body temperature C. has its body temperature determined primarily by the environment and has a broad range of body temperature variation D. behaviorally regulates its body temperature and has a broad range of body temperature variation E. uses metabolic energy to regulate its body temperature but has a broad range of body temperature variation
Answer: The correct option is A (uses metabolic energy to regulate its body temperature and maintains a relatively constant body temperature).
Explanation:
HOMOEOTHERMIC animals are also called endothermic animals. They are the warm blooded animals which uses heat energy generated metabolically to regulate and maintain a relatively constant body temperature. Examples of animals that are endothermic include the birds and mammals.
The temperature which they maintain is deep inside the body and not the skin temperature.
Also the temperature of a body is affected by the heat it gains and losses. The body gains heat mainly:
--> by absorbing it from its surroundings
--> from the heat released during the catabolic reaction that occur all the time in the body cells.
--> by conduction, convection and radiation from the surface of the body
--> through evaporation, especially of sweat and
--> in the air that is exhaled and urine that leaves the body.
Under normal circumstances, the heat the body gains is balanced by the heat it loses. A RISE in body temperature stimulates the following processes to get rid of excess body heat:
--> A decrease in metabolic rate: the body slows down its activities to decrease the metabolic rate. This reduces the heat released by metabolic reactions, hence minimizing heat production within the body.
A FALL in body temperature stimulates the following processes to produce and conserve heat:
--> increasing metabolic rate: The body increases its metabolic rate, especially that of the liver, to produce more heat
One end of the rope is vibrated to produce a wave with a wavelength of 0.25 m. The
Frequency of the wave is 3.0 Hz. What is the speed of the wave? *
1)3.00m/s
2)2.50m/s
3)0.75m/s
4)1.25m/s
Answer:
3) 0.75m/s
Explanation:
The wavelength of a wave is calculated using the formula;
λ = v/f
Where!
λ = wavelength of wave (m)
v = velocity or speed (m/s)
f = frequency of wave (Hz)
According to this question, one end of a rope is vibrated to produce a wave with a wavelength (λ) of 0.25 m and frequency (f) of 3.0 Hz.
Using λ = v/f
v = λ × f
v = 0.25 × 3
v = 0.75m/s.
