Answer:
Lymphocytes
Explanation:
A lymphocyte is a type of white blood cell that is part of the immune system. There are two main types of lymphocytes: B cells and T cells. The B cells produce antibodies that are used to attack invading bacteria, viruses, and toxins. The T cells destroy the body's own cells that have themselves been taken over by viruses or become cancerous.

place each of the labels in the proper position to denote whether they would pass through the filtration membrane or not.
The labels that will pass through the filtration membrane are water, glucose, and sodium.
The labels that will not pass through the filtration membrane are red blood cells, lymphocytes, antibodies, and platelets.
The filtration membrane is a microporous glomerular barrier membrane made of polymeric materials that are used for the separation and filtration of substances based on their molecular weight.
Depending on the molecular size of a substance situated in the blood, we can determine if such substances can be filtered through the filtration membrane or not.
However, the lower the molecular weight of the substance, the higher their likelihood of filtration.
In the plasma, the substance that has a lower molecular weight are water, glucose, and sodium while substance associated with protein, blood cell, and platelets contains higher molecular weight.

enzymes that cleave nucleotides from the ends of a dna molecule are known as what?
Enzymes that cleave nucleotides from the ends of a DNA molecule are known as Restriction endonucleases.
What are Enzymes?Enzymes may be defined as the type of biocatalysts that significantly increase the rate of a chemical reaction without being changed in the overall process. It is thought that all cellular reactions and processes are mediated by enzymes.
Restriction endonucleases are the enzymes that are also called molecular scissors which are responsible for cutting DNA at specific sites. These enzymes are present in bacteria in order to provide a defense mechanism called the restriction modification system.
There are various types of restriction enzymes are known. For example, BamH1, EcoRI, Hind III, etc.
Therefore, restriction endonucleases are the enzymes that cleave nucleotides from the ends of a DNA molecule.

The concentration of sodium on the inside of the cell is 20 mM. The outside of the cell has a sodium concentration of 115 mM. Which mechanism of ion uptake would best move sodium from the inside of the cell to the outside? osmosis diffusion passive transport active transport.
Answer:
It's active transport
Explanation:
The mechanism of ion uptake that would best move sodium from the inside of the cell to the outside is active transport.
What do you mean by Ion uptake?Ion uptake may be defined as the process of movement of ions from one side of the membrane to the other.
Active transport helps in the movement of ions against the concentration gradient. It also requires energy. The active transport of small molecules or ions across a cell membrane is generally carried out by transport proteins that are found in the membrane.
Therefore, the mechanism of ion uptake that would best move sodium from the inside of the cell to the outside is active transport.

What evidence of climate change on continents supports the theory of continental drift?
signs that glaciers existed in South Africa
similar coal fields on different continents
change in atmospheric temperature over time
same animal fossils found on different continents
Answer:
A
Explanation:
Edge2022
The evidence of climate change on continents that supports the theory of continental drift is similar coal fields on different continents. Hence option B is correct.
What is continental drift theory?The theory of continental drift suggests that the Earth's continents were once joined together in a single landmass called Pangaea, which began to break apart around 200 million years ago.
This idea was first proposed by German scientist Alfred Wegener in the early 20th century, who noticed the striking similarities between the coastlines of Africa and South America.
Coal is formed from the remains of plants that lived millions of years ago, and its distribution can provide clues about how continents were once connected.
Coal fields found on different continents that match in age and composition indicate that the continents were once joined together in a larger landmass.
This supports the theory of continental drift, which states that the continents were once part of a single supercontinent that later broke apart and drifted into their present positions.
This evidence suggests that coal-forming swamps once existed in locations that are now separated by oceans and that these locations were once connected.
Hence option B similar coal fields on different continents is correct.

when was the last time that you had your vital signs taken ?how was the result?
Answer:
Normal vital sign ranges for the average healthy adult while resting are: Blood pressure: 90/60 mm Hg to 120/80 mm Hg. Breathing: 12 to 18 breaths per minute. Pulse: 60 to 100 beats per minute.Vital signs are measurements of the body's most basic functions. The 4 main vital signs routinely checked by healthcare providers include: Body temperature. Pulse rate.Checking vital signs is an important skill to learn, because it tells us how the person's body is functioning, helping us to monitor current conditions and alerting us to changes in health status. It can also give us clues to possible medical conditions that have yet to be diagnosed.

A blood and is heterozygous for the trait and the father has type AB blood?
Answer:
50%
Explanation:
To solve this, we'd need to use a Punnett square. Since the mother has a heterozygous genotype and has an A-blood phenotype, we know that she is AO and the father is AB.
A B
A AA AB
O AO BO
According to this, the four possible blood types, with equal probability are: AA, AB, AO, and BO. Both AA and AO genes will result in type-A blood, since A is dominant over O. Therefore, there is a 2 in 4 (or 1 in 2, or 50%) chance of the child having type-A blood.

Explanation:
Mechanical digestion is a purely physical process that does not change the chemical nature of the food. Instead, it makes the food smaller to increase both surface area and mobility. It includes mastication, or chewing, as well as tongue movements that help break food into smaller bits and mix food with saliva.
