What prevents blood from circulating backward in veins?
A.valves
B. capillaries
C. lungs
D. heart
Answer:
A.Valves
Explanation:
The pulmonary vein empties oxygen-rich blood from the lungs into the left atrium. As the atrium contracts, blood flows from your left atrium into your left ventricle through the open mitral valve. When the ventricle is full, the mitral valve shuts. This prevents blood from flowing backward into the atrium while the ventricle contracts.
The
store(s) more carbon than the atmosphere.
O rock
trees
oceans
Osoil
Answer:
Oceans
The oceans are a massive carbon sink, and part of the positive reinforcement of the greenhouse gas cycle is that, as the oceans become warmer, then tend to release more carbon dioxide dissolved in the water which in turn drives temperatures warmer.
The dichotomous key below provides a way to classify some animals into groups according to their physical characteristics. The key can be used to classify each of the four animals represented below. Which answer choice shows the correct classification group for each animal? 1. Wasp = group D; Ant = group D; Tiger = group A; Bird = group B 2. Wasp = group B; Ant = group A; Tiger = group D; Bird = group C 3. Wasp = group B; Ant = group D; Tiger = group A; Bird = group C 4. Wasp = group D; Ant = group A; Tiger = group A; Bird = group B
Complete question:
The dichotomous key below provides a way to classify some animals into groups according to their physical characteristics.
Dichotomous Key
I wings------------------go to II
no wings------------- group A
II feathers---------------group B
no feathers----------go to III
III two legs------------- group C
six legs---------------group D
The key can be used to classify each of the four animals represented below ⇒ wasp, ant, tiger, bird
Which row in the chart shows the correct classification group for each animal?
Row Wasp Ant Tiger Bird
(1) group D group D group A group B
(2) group B group A group D group C
(3) group B group D group A group C
(4) group D group A group A group B
Answer:
Row Wasp Ant Tiger Bird
(4) group D group A group A group B
Group A: Tiger and Ant → They do not have wingsGroup B: Bird → It has wings and feathersGroup D: Wasp → It has wings, does not have feathers, and has six legsExplanation:
When analyzing a dichotomous key, you just need to pay attention to the given descriptions and carefully observe the organisms you have.
The key describes specific morphological traits of each organism that are useful to differentiate it from other organisms. So all you need to do is to follow the instructions given in each step, and the key will guide you directly to the answer.
In the exposed example you have four organisms: wasp, ant, tiger, bird
The provided key gives you three steps: I, II, III.
Step I:
wings------------------go to II
no wings------------- group A
Here the key tells you to separate, from your group of organisms, the ones that have wings from the ones that do not have wings.
wasp and bird have wings → So you need to go to step IItiger and ant do not have wings → So they belong to Group AStep II:
feathers---------------group B
no feathers----------go to III
Now you only need to consider the bird and the wasp, which are the two organisms that have wings.
Here the key tells you to separate the one that has feathers from the one that does not have feathers.
Bird has feathers → So it belongs to the group BThe Wasp does not have feathers → So you need to go to step IIIStep III:
two legs------------- group C
six legs---------------group D
In this last step, the key takes you to two possible groups. But you only have one left organisms, which is the wasp. So what you need to do is to observe how many legs your wasp has. It is an insect, so it has six legs. The wasp belongs to Group D.
You do not have any organism that belongs to group C.
To sum up, according to the given information you could group the group of organisms as follows:
Group A: Tiger and Ant → They do not have wingsGroup B: Bird → It has wings and feathersGroup D: Wasp → It has wings, does not have feathers, and has six legs2. The formation of male and female sex cells is known as

SO you hopefully selected that an Allele is a form of a gene. BUT what is this really...
A. an allele is a protein that causes hair no hair in the guinea pig
B. an allele is a length of DNA with a specific sequence of nitrogen bases that make a protein that results in Hair or No Hair on the guinea pig
Answer:
B. an allele is a length of DNA with a specific sequence of nitrogen bases that make a protein that results in Hair or No Hair on the guinea pig
Explanation:
An organism that has two different alleles of the gene is called heterozygous. Phenotypes (the expressed characteristics) associated with a certain allele can sometimes be dominant or recessive, but often they are neither.
B. an allele is a length of DNA with a specific sequence of nitrogen bases that make a protein that results in Hair or No Hair on the guinea pig

What is the function of the class of macromolecules represented in the following diagram
Answer:
lods ayarn na:)
Explanation:
The four classes of biological macromolecules are (1) Proteins, (2) Lipids, (3) Carbohydrates, (4) Nucleic Acids.
Proteins are made up of amino acids linked by peptide bonds. They have multiple functions, depending on the number of amino acids and its specific sequence. They serve as major workers composing motor and structural elements in the cell. They can also function as catalytic proteins (enzymes), as well as helpers for storage, signal, transport, reception, defensive, and contractile tasks.
Lipids are made up of fatty acids (a carboxylic acid with a hydrocarbon chain + terminal carboxyl group) and glycerols (organic compound made up of multiple hydroxyl groups). They are a hydrophobic compound that are used for energy storage, thermal insulation, protection, and chemical messengers. Lipids also regulate membrane permeability and aid in fat soluble vitamin production.
Carbohydrates are made up of monosaccharides which build up a polysaccharide (carbohydrates). Monosaccharides are basic sugars which cannot be broken down anymore by water (glucose, fructose, galactose). Carbohydrates' major functions include energy provision, blood glucose regulation, biological processes recognition, and breakdown of fatty acids for ketosis prevention.
Nucleic acids are made up of nucleotides which are organic molecules that forms the Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA). Their structure consists of a nitrogenous base, pentose, and an attached phosphate group. The function of nucleic acids are the creation and storage of genetic information.
The kidneys are organs that are involved in which process in mammals?
Answer: The urinary system
Explanation:
Answer:
Kidneys regulate the osmotic pressure of a mammal's blood through extensive filtration and purification, in a process known as osmoregulation. Kidneys filter the blood; urine is the filtrate that eliminates waste from the body via the ureter into the bladder.

Part B:
Which BEST describes the result of this mutation?
A
The entire sequence of amino acids is changed.
B
The RNA strand does not code for the correct amino acids.
С
The change in amino acids shortens the polypeptide sequence.
D
The alternation of a single nucleotide encodes for a different amino acid.
Answer:
A . The entire sequence of amino acids is changed.
Explanation:
The entire sequence of amino acids is changed when the mutation occurs in the protein because amino acid is the building block from which protein is made. Mutation is the sudden change that is occur in the genetic makeup i.e. DNA when the cell is exposed to radioactive radiation of chemicals. So due to this change, the sequence of amino acids changed and they work differently.

Discuss how a soil, a natural body, differs from soil, a
material that is used in building a roadbed.
Answer:
Soil is a material made up of gases, organic substances, water, and microorganisms. This material may be used in building a roadbed and is often referred to as dirt. In comparison, a soil is a natural body that is three-dimensional much like a lake or mountain.
Explanation:
Hope this helps
Gases, organic materials, water, and microbes are all components of soil. This substance, which is frequently referred to as dirt, can be utilized to construct a roadbed. In contrast, the soil is a three-dimensional natural structure similar to a lake or a mountain.
What is soil?Soil is the loosely packed organic or mineral material that makes up the Earth's immediate surface and acts as a habitat for land plants. The unconsolidated organic or mineral matter that has been exposed to relief-conditioned macro- and microbes operating on parent material throughout time, as well as genetic and environmental factors such as climate (including water and temperature effects). A product-soil is distinct from the source material in many ways, including in terms of its physical, chemical, biological, and morphological qualities.This is how natural soil is different from the material used in constructing roadbeds.
