Answer:
Haploid describes a cell that contains a single set of chromosomes. The term haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes. In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells.
What is the action force and the reaction force when someone swims?
No link
Answer:
The action and reaction forces are reciprocal (opposite) on an object. The swimmer pushes against the water (action force), the water pushes back on the swimmer (reaction force) and pushes her forward. The ball puts a force on the wall (action force), and the wall puts a force on the ball (reaction force) so the ball bounces off.
Explanation:
Answer:
the force is push and the reaction is moving forward.

Studies indicate that acidification of the ocean by the absorption of carbon dioxide is harmful to virtually all marine life and ecosystems. The group most vulnerable to both warming and acidification would be the _________. View Available Hint(s) Studies indicate that acidification of the ocean by the absorption of carbon dioxide is harmful to virtually all marine life and ecosystems. The group most vulnerable to both warming and acidification would be the _________. marine mammals krill and other zooplankton reef corals and other calcareous organisms benthic crustaceans pelagic fishes
Answer:
The correct answer is - reef corals and other calcareous organisms.
Explanation:
Acidification of the ocean is the continuous uptake of carbon dioxide from the atmosphere and reducing the pH of the water of the ocean. The acidification and warmth due to increasing the carbon dioxide in water cause harmful effects on the life of all marine life.
It affects coral reefs and other calcareous organisms as well as other organisms. These calcareous organisms required more efficiency to repair their cells or have to thickening of layers to survive in case of acidification of the ocean or to
what is the different between mechanical digestion and chemical digestion in the mouth?
Answer and Explanation:
The mouth is part of the digestion system.
Mechanical Digestion is the physical motion our mouth makes to chew up the food. We grind up the food with our teeth, then swallow the food into the next part of the digestive system.
Chemical Digestion in the mouth is the saliva our mouth produces. It breaks down the food along side the mechanical part of the mechanical digestion.

Which statement is most consistent with the theory of Natural Selection?
a. Individual organisms learn to adapt to changes in their environment in order to
survive.
b. Different species breed with each other to produce offspring with new helpful
characteristics.
c. Organisms that are best suited to survive will pass their traits onto their offspring.
d. All changes in the environment cause mutations that help organisms.
Answer: C. Organisms that are best suited to survive will pass their traits onto their offspring.
Explanation: Natural selection is the process where organisms better adapted to their environment tend to survive. This allows them to pass their traits onto the offspring for better survival.
Alex is studying a population of fifty organisms that belong to the same species. Some of the organisms have dark spots, some have light spots, some have no spots, and some have stripes.
How does this species most likely reproduce?
Answer:
Sexual reproduction
Explanation:
There is a significant amount of genetic variation (diversity) here. Asexual reproduction results in little to no diversity, so we can assume this species reproduces sexually. Hope it helps :)
can racial categories be determined by biological traits?
Scientists have been studying four populations in a swamp area. In this area, alligators eat gar (a type of large fish), and both gar and diving ducks eat crabs. The data showed that recently the alligator population has decreased. How could the decrease in the alligator population affect the other populations? Be sure to explain whether the gar population, the diving duck population, and the crab population will change, and why.
Answer:
There wouldn't be enough resources for the alligator population to live off of thus decreasing its population number. This decrease affects the other populations because it without alligators, its predators and prey wouldn't gain its nutrition from it and it would overall change its environments' habitation. The gar population would increase because they wouldn't be eaten by the alligators and therefore increasing the diving duck population as well. The crab population would decrease because the gar (their prey) population increased which overcomes the number of crab in the population.

Do you use potentially hazardous products in your home in a way that’s safe for humans and safe for the environment? Explain.
Answer:
No.
Explanation:
The question says it all even though it safe for humans and the environment it still has the potential to become hazardous given the right conditions
In humans, hair color and hair type are controlled by simple dominance. Brown hair (B) is dominant over blonde hair (b). Straight hair (H) is dominant over curly hair (h). A man who is heterozygous for brown hair and also has curly hair is crossed with a blonde-haired woman who is heterozygous for straight hair.
Answer:
These are the possible phenotypes of the offspring
In humans blood type A and B are equally dominant (codominant). Both types are dominant to type O. Aman with type AB blood marries a woman with type O blood, give the genotype and phenotype of all possible offsprings
Answer:
The correct answer would be -
Genotype: IAIO or IBIO
Phenotype: A Blood or B Blood
Explanation:
Blood group A and blood group B both are dominant over the blood group O, however, both A and B are codominant if present together and form the blood group AB.
The blood group of Aman is AB and If he marries the female with O blood group then possible blood group in offspring would be as follows:
gametes: Aman = IA and IB
woman = IO IO
then cross between:
IA IB
IO IAIO IBIO
IO IAIO IBIO
the genotype of this cross would be 50% chances of IAIO and 50% chances of IBIO and phenotype would be either Type A or type B.

1. What causes the tectonic plates to move?
2. How did the creator of this video explain why
some plates are moving faster than others?
3. What are the 3 main types of plate boundaries?
Answer: 1. The heat from radioactive processes within the planet's interior causes the plates to move, sometimes toward and sometimes away from each other. This movement is called plate motion, or tectonic shift. 2. But scientists were at a loss to explain why some pieces of crust move much faster than others. A new study suggests these tectonic plates control their own speed more than the mantle does. ... The velocities of these plates and the velocities of the boundaries between these plates vary significantly on Earth." 3. Divergent boundaries -- where new crust is generated as the plates pull away from each other.
Convergent boundaries -- where crust is destroyed as one plate dives under another.
Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.

The drawing below illustrates a small portion of the molecules that make up a cell membrane. What is the purpose of the phospholipid molecules?
Answer:
Although there is no picture....
Explanation: Phospholipids protect cells by acting as barriers in their membranes, and they also act as barriers for the organelles within those cells. Phospholipids serve as conduits for different substances to pass across membranes.
If CO2 is a molecule, how many TOTAL atoms is it made
up of?
Answer:
Carbon dioxide, CO2, is a chemical compound composed of two oxygen atoms and one carbon atom.
Explanation:
Answer: No number means one atom. For CO2 there is one atom of carbon and two atoms of oxygen. For H2O, there is one atom of oxygen and two atoms of hydrogen. A molecule can be made of only one type of atom.

How many days are in between moon phases, and if there was a new moon on March 17, when will the next new moon be?
Answer:
It takes 27 days, 7 hours, and 43 minutes for our Moon to complete one full orbit around Earth. This is called the sidereal month, and is measured by our Moon's position relative to distant “fixed” stars. However, it takes our Moon about 29.5 days to complete one cycle of phases (from new Moon to new Moon).

What do proteins have to do with your traits?
Answer:
Proteins are molecules made of amino acids. They are coded for by our genes and form the basis of living tissues. For example, proteins catalyse reactions in our bodies, transport molecules such as oxygen, keep us healthy as part of the immune system and transmit messages from cell to cell.
