Answer: If mammalian cells receive a go-ahead signal at the G1 checkpoint, they will D. complete the cycle and divide. G1 checkpoint occurs between the G1 and S phase of the cell cycle. When the cell is grown sufficiently and produces all components of DNA replication it enters in the S phase.
If mammalian cells receive a go-ahead signal at the G1 checkpoint, they will complete the cell cycle and divide.
What is cell cycle?The cell cycle, or cell-division cycle, is the series of events that take place in a cell that cause it to divide into two daughter cells.
Moreover, a cell cycle is a series of events that takes place in a cell as it grows and divides. A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.
The cell cycle consists of a series of steps during which the chromosomes and other cell material double to make two copies. The cell then divides into two daughter cells, each receiving one copy of the doubled material.

which protist is not correctly linked to the type of movement it shows?
Answer:
Sporozoa-flexing the pellicle
Explanation:
Sporozoa do not have flagella, cilia, or pseudopodia and they show gliding movement, amoeboids show movement by pseudopodia, ciliates by cilia and zooflagellates show by flagella, the pellicle is shown by paramecium.
So, the correct option is 'Sporozoa-flexing the pellicle'.
Scientists can study the human genome using DNA fingerprinting.
DNA fingerprinting allows scientists to
B. break the hydrogen bonds in a gene to allow DNA to replicate itself.
c. determine the location of an abnormal gene on an individual's
chromosome.
A. prevent a gene from matching complementary bases onto a strand of
RNA.
Answer:
your answer is C.
Explanation:
DNA fingerprinting allows researchers to determine the location of an abnormal gene in a person's chromosomes.
What are the steps in DNA fingerprinting?DNA fingerprinting is a laboratory technique used to determine the likely identity of a person based on the nucleotide sequences of certain regions of a person's DNA that are unique to individuals.
DNA fingerprinting was used early in legal disputes, particularly in solving crimes and establishing paternity. It is also used to detect inherited genetic diseases and can be used to identify genetic matches between tissue donors and recipients.
In DNA fingerprinting, researchers collect DNA samples from various sources, such as hair from crime scenes and blood from victims and suspects. They then narrow down scattered sections of repetitive DNA in these samples.

As a result of higher osmotic gradient outside, ____________ moves out of the thin descending limb of Loop of Henle
Answer:
is it water?
Explanation:
As a result of higher osmotic gradient outside, water moves out of the thin descending limb of Loop of Henle.
What is osmotic potential?Osmotic potential is a component of water potential whose magnitude depends on the amount of solutes present in the solution, with osmotic pressure defined as the pressure necessary to prevent osmosis from occurring.
The loop of Henle (or nephr), in anatomy, is the segment of the nephron that comes just after the proximal convoluted tubule, being a U-shaped tubular structure, with a thick and a thin portion. That can be done with the osmotic potential.

The cell in the diagram is a plant cell because it has chloroplasts and a cell wall.
There are two types of cells animal cells, which are the ones that humans and animals have, and plant cells, which are the ones that plants and trees have. They share some organelles, but they also have some that are specific to each type.
The plant cell parts in the picture are:
Rough Endoplasmic Reticulum: it is where the ribosomes are. The synthesis of proteins happens there.Chloroplast: it is an organelle-specific of plant cells. They are in charge of photosynthesis.Cell wall: it is only present in plant cells. It surrounds the membrane.Mitochondria: It is the place that generates the energy that the cell needs.Vacuole: they are bigger in cell plants than in animal plants. It has many functions, but one is to store water.Membrane: it draws the limits of the cell.Golgi Apparatus: it is the place where proteins go to be distributed.Nucleus: it contains DNA, and it has a membrane around it.The nucleolus: is the larger part of the nucleus. It is in contact with the endoplasmic reticulum.To sum up, the plant cell has a bigger vacuole than the animal cell; it also has chloroplasts and a cell wall, which are not present in the animal cell.

All vertebrate brains include a hypothalamus. In humans, it stands the size of an almond.
The hypothalamus stands answerable for the regulation of specific metabolic functions and other actions of the autonomic nervous system. It synthesizes and secretes certain neurohormones, named releasing hormones or hypothalamic hormones, and these, in turn, promote or inhibit the secretion of hormones from the pituitary gland. The hypothalamus influences body temperature, hunger, important aspects of parenting and affection manners, thirst, fatigue, sleep, and circadian rhythms.

The diagram shows the approximate amounts of carbon, in gigatons (Gt) per year, that move through the primary processes
of the carbon cycle. The numbers in yellow are due to natural processes, and the numbers in red are the result of human
actions. Based on this diagram, complete the statements.
Human activities release 9 gigatons of carbon into the atmosphere each year.
Human activities remove 5 gigatons of carbon from the atmosphere each year.
Humans’ net contribution of atmospheric carbon to the atmosphere is 4 gigatons each year.
9 gigatonnes of carbon are released into the atmosphere annually by human activity. Each year, 5 gigatonnes of carbon are removed from the atmosphere by human activity.
Thus, Each year, 4 gigatons of atmospheric carbon are added to the atmosphere as a result of human activity.
A fundamental mechanism that controls the movement of carbon dioxide and other carbon compounds between the atmosphere, oceans, soil, and living things on Earth is known as the carbon cycle. The concentration of carbon in various reservoirs is influenced by a variety of natural and human factors.
Plants and other photosynthetic creatures take up about 120 Gt of carbon each year from the atmosphere through the process of photosynthesis (yellow).
Thus, 9 gigatonnes of carbon are released into the atmosphere annually by human activity. Each year, 5 gigatonnes of carbon are removed from the atmosphere by human activity.
