when was the last time that you had your vital signs taken ?how was the result?​

Answers

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.

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.

Answers

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 is the probability that a couple will have a type A child if the mother has Type
A blood and is heterozygous for the trait and the father has type AB blood?

Answers

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.

place each of the labels in the proper position to denote whether they would pass through the filtration membrane or not.

Answers

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.

A frameshift mutation that results in the insertion of three nucleotides is often less deleterious than a mutation that results in the insertion of one nucleotide. Why?

Answers

A frame shift mutation that results in the insertion of 3 nucleotides doesn’t reading frame of the downstream codons and proteins they will be made into.

A mutation that inserts a single nucleotide ultimately will change the reading frame and all of the codons (3 nucleotides) downstream of that insertion will make a different protein than they were suppose to or a stop codon could be made which will completely stop that protein from being made.

Example: AUG UAU ACU CAC
The example above will encode for the following proteins.

met, Tyr, Thr, His

3 nucleotide insertion in this example could be:

AUG UAU AAU ACU CAC

met, Tyr, Asn, Thr, His

1 nucleotide insertion mutation:

Example: AUG UAA U ACU CAC

Met, stop codon

Nucleotides after the A insertion are not made into proteins.

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

Answers

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.
