Answer:
There are three main types of blood vessels
The arteries (red) carry oxygen and nutrients away from your heart, to your body's tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart.

How can a star be extremely hot like Alpha Canis Majoris (4 times hotter than our sun) but give off so little light (only 2% of our sun’s light)?
It's on Earth Science.
Answer:
this is due to the fact that stars are suns of other galaxy as we know that we have about a million galaxies in space. the earth is located in the milky way galaxy so these stars are about a 150 billion kilometres from earth
Solar radiation is a broad word for the electromagnetic radiation that the sun emits. It is also sometimes referred to as the solar resource or just sunshine. A multitude of devices can be used to collect solar radiation and transform it into useful forms of energy, such as heat and electricity.
How much of the Sun do we actually see?Sunlight at Earth's surface is roughly 42 to 43 percent visible (400 to 700 nm), 52 to 55 percent infrared (above 700 nm), and 3 to 5 percent ultraviolet in terms of energy (below 400 nm).The Sun always emits the same amount of energy. Insolation refers to the incoming solar radiation. Seventy percent of solar energy makes it to the planet.99.8% of the mass in our solar system is found in the Sun. Everything, from tiny Mercury to the gas giants to the Oort Cloud, 186 billion light-years away, is kept in place by its gravitational attraction.What would occur if our distance from the Sun increased by 10%?More radiation, ultraviolet rays, heat, and other rays would be directed at our atmosphere. It would be impossible to live. According to my projection, the global average temperature would increase from 16 C to 65 C. (149 Fahrenheit). This would be high enough to prevent most life from existing, yet low enough to prevent water from boiling.The solar system itself, the Sun Between 99.8 and 99.9 percent of the mass of the solar system is found in the Sun. The remaining matter is distributed among the planets and their satellites, asteroids, comets, and the gas and dust that surrounds our star.To learn more about Solar radiation, Refer:

true or false? a haploid organism has one pair of homologous chromosomes.
Answer:
False
Explanation:
A haploid has one SET of homologous chromosomes
It is false that a haploid organism has one pair of homologous chromosomes.
What are haploid organisms?When an organism's cells only have one set of chromosomes, the organism is said to be haploid.
All organisms that reproduce are diploid (having two sets of chromosomes, one from each parent). Only the egg and sperm cells in humans are haploid.
Male ants, bees, and wasps are haploid organisms because they develop from unfertilized haploid eggs, whereas females (workers and queens) are diploid, making their system haplodiploid. The majority of animals are diploid.
The term "diploid" describes how many complete sets of chromosomes there are in each cell of an organism: diploid cells have two entire sets.
On the other hand, haploid organisms only have one complete set of chromosomes. Throughout meiosis and sporadically in mitosis, chromosome sets can change.
Thus, the given statement is false.

diffusion is the net movement of __ through a semipermeable membrane based on a concentration gradient.
Answer:
Molecules
Diffusion is the net movement of molecules through a semipermeable membrane. It goes from high concentration to low concentration.
Diffusion is the net movement of molecules through a semipermeable membrane based on a concentration gradient.
What is diffusion?
Diffusion has the net movement of molecules through a semipermeable membrane. It goes from high concentration to low concentration. Osmosis has been the process in which molecules of the solvent pass via a semipermeable membrane from a lower concentrations to higher concentration or from less concentrated solution to high concentrated solution. In the process of osmosis movement of water takes place.
There are mainly three types of osmosis and these are hypertonic, hypotonic, and isotonic. The process of osmosis is passive transport as water moves from low solute concentration to high solute concentration.
Osmosis has been also known as diffusion of water or solvent via a membrane which allows only selective substance to go across the channel. The process of osmosis does not require ATP because it is a passive process.
Therefore, Diffusion is the net movement of molecules through a semipermeable membrane based on a concentration gradient.

Why do the functions of many receptor kinases depend on the fluid nature of the plasma membrane?
The generation of cAMP requires a fluid membrane.Binding of ligand to the receptor requires a fluid membrane. The receptor monomers must move together and dimerize to be activated. Phosphorylation requires a fluid membrane.We have that
The reason why the functions of many receptor kinases depend on the fluid nature of the plasma membrane is because
Phosphorylation requires a fluid membrane.

series of reactions in which particles from one reaction trigger the next reaction.
Explanation:
If your a connexus student here for the Modeling Nuclear Processes Quick Check, here are the answers!
1-the process by which small nuclei combine into a larger nucleus
2-a series of reactions in which particles from one reaction trigger the next reaction
3-disturbing a drop of water such that it breaks into smaller droplets
4-popping a bag of popcorn
5-The resulting nucleus is more stable than the original nucleus. The nucleus can be of a different element than the original.

A nuclear chain reaction happens when a single nuclear event averages out one or more further nuclear reactions, opening the door for a potentially endless chain of similar processes. Therefore, option (A) is correct.
What is a nuclear chain reaction ?A nuclear chain reaction happens when the output of one nuclear reaction triggers the occurrence of further nuclear reactions. These cascade reactions are nearly invariably a succession of neutron-excessive fission events. The moniker "chain reaction" comes from the fact that these extra neutrons have the potential to trigger more fission events. The functioning of nuclear power plants depends on nuclear chain reactions.
About a million times more energy is released during nuclear reactions than during chemical ones. Every fission event must result in precisely one additional fission event in order for a nuclear chain reaction to continue.
Therefore, option (A) correctly describes the nuclear reaction.

(c) Make a claim about the most immediate effect on the fused B-cancer cells if the fused cells are transferred to a growth medium that lacks a source of nitrogen.
Answer:
CLAIM: IF THE FUSED B CANCER CELLS ARE GROWN IN A MEDIUM THAT DOES NOT CONTAIN NITROGEN SOURCE, THE CELLS WILL STOP SYNTHESIZING PROTEINS AND THEIR LIFE SPAN WILL BE GREATLY REDUCED
Explanation:
The growth medium that was used to reproduce the fused cancer B cells contains nitrogenous compounds that serves as source of nitrogen for the production of nitrogenous bases of DNA, If the nitrogen source is removed, the DNA in the nucleus of the white blood cell will lack adenine and guanine, which are necessary for the synthesis of DNA molecules.
2. Nitrogen is an integral part of DNA and protein. Nitrogen is needed to produce nitrogenous bases that are found in DNA. The DNA molecule is the one that initiate and direct the synthesis of protein in living cells.
In the fused B cancer cells, DNA must be produced, so that the dividing cancerous cells can continue their uncontrolled division, this will keep the cells alive. Nitrogen is also needed for the continuous synthesis of the special protein that the fused B cell is producing.
Thus, if nitrogen source is removed from the growth medium used for the cultivation of fused B cells, then the cells will stop synthesizing protein, their life span will be greatly reduced and they will eventually die out.
