consider a cross between two individuals whose genotypes for two different loci are AaBb and AaBb. predict the outcomes of this cross. from the options below. select all that are possible from this cross
Answers
Answer:
It’s A,B,E!!
Explanation:
I just did it on USATestPrep!!
In dihybrid cross due to independent assortment if the cross between genotypes for two different loci is AaBb and AaBb, the outcomes are 1/16 progeny will be AABB and 1/16 is aabb, and 1/4 offspring will be AaBb like parents, hence option a,b,e is correct.
What is a dihybrid cross?In 1865, Gregor Mendel performed dihybrid crosses on pea plants and found the Property of Independent Assortment, a basic law of genetics.
He developed the dihybrid cross based on the same rules as a monohybrid cross. He determined the phenotypic ratio (9:3:3:1) seen in a dihybrid cross for a heterozygous cross from these investigations.
The Cross between AaBb and AaBb is shown in punnet square in the diagram below, and the outcomes are 1/16 progeny will be AABB and 1/16 is aabb, and 1/4 offspring will be AaBb.
Therefore due to independent assortment in the dihybrid cross, options a,b, and e is correct.

Working-class women were expected to help their husbands run their business. They were denied all political rights and considered legally subject to their husbands.
The plague nearly destroyed Italy's economy ↔ It became harder and harder to find people to plow fields, harvest crops, and produce other goods because of the amount of people dying. Peasants also began to demand higher wages. Lasted from 1629 to 1631 and killed more than 45,000 people in Venice alone. It wiped out over half the population.

Answers
Answer:
Cells of the immune system are able to respond to the presence of invading organisms because they recognize the antibodies present in the invading pathogen
Explanation:
The mechanisms of human immunity can be grouped into two broad categories: the innate or nonspecific immune system, which provides a first and general defense against any element recognized as foreign, and the acquired or specific immune system that recognizes specific threatening agents and generates a response directed against those elements. When foreign substances enter our body (bacteria, viruses, parasites, proteins from other animal or plant species, cells from other organisms - including those of human origin - and a long etcetera, all of which are given the common name of antigens) and are brought into contact with cells that are members of the immune system, the foreign element or antigen is first captured by certain types of cells that are collectively known as antigen-presenting cells. These cells would correspond to the intelligence service and their mission is to take the antigens, introduce them inside, process them and present the antigens on their surface in a fragmentary way to other cells of the immune system. This results in the activation of lymphocytes that specifically recognize the antigen and ends in the development of mechanisms that mediate the physiological function of the response, that is, the elimination of the antigen. Thus, the immune response can be functionally divided into three phases: the antigen recognition phase, the activation phase of the response, and the effector phase.

The primary forms of energy are light, mechanical, chemical, nuclear, electrical, heat, and sound.
Energy only convert from one form to another is known as energy transformation or conversion.
The Sun is the primary source of energy that is nuclear energy changed into electromagnetic energy like light energy.
This light energy travels in the form of waves reach the earth surface taken up by plants for doing photosynthesis.
Now light energy is converted into chemical energy which can be used up by animal and human in their food.
The chemical energy of the food converted into heat and mechanical energy which maintain the body’s temperature and involve in various physiological process like motion, breathing, standing, or running.

if the checkpoint finds an error, what are some actions the cell can take to ensure the error does not get replicated?
Answers
Answer:
If the checkpoint mechanisms detect problems with the DNA, the cell cycle is halted, and the cell attempts to either complete DNA replication or repair the damaged DNA. If the damage is irreparable, the cell may undergo apoptosis, or programmed cell death 2.
Explanation:
um i think this is correct. hope this helps and have a nice day
-KindnessMatters-
The cell cycle is the intricate process of replication of genetic material and producing the daughter cells. The cell cycle is regulated by several mechanisms, one of which is checkpoints.
Checkpoints are the sites where the cells are checked for errors and inaccuracy in the cell.
The cell takes action to ensure errors are not replicated as:
The G1 checkpoint in the cell cycle is the primary checkpoint, which decided whether the cell should divide or not divide. It checks for size, DNA damage, and nutrients. The cell cycle will halt if there will be any errors. The G2 checkpoint is involved in the overall smoothening of the cell cycle. If any damage is observed after the other checkpoints, the cell cycle will pause in the G2 phase, halting the replication of errored genetic material.The M checkpoint corresponds to accurate attachment of the sister chromatids and the cycle will be in pause if the proper attachment is not done.
Thus, there are several checkpoints to check the errors in the DNA, and if any error persists, the cell cycle will be halted.

What conditions are necessary for rocks to melt? ( I’ll give a Brainliast) please answer
Answers
Answer:
The rock is pulled down by movements in the earth's crust and gets hotter and hotter as it goes deeper. It takes temperatures between 600 and 1,300 degrees Celsius (1,100 and 2,400 degrees Fahrenheit) to melt a rock, turning it into a substance called magma (molten rock).
Answer:
Flux melting occurs when water or carbon dioxide is added to rock. These compounds cause the rock to melt at lower temperatures. This creates magma in places where it originally maintained a solid structure. Much like heat transfer, flux melting also occurs around subduction zones.

Hey y'all I need help with this bio question: what are the pros and cons of different skin tones in different parts of the world?
Answers
It basically all boils down to Vitamin D! We need this essential vitamin to help our body build hormones and regulate calcium. Our bodies make Vitamin D when we are exposed to the UV rays found in sunlight. But as we all know, too much sunlight isn’t good because these UV rays can harm us. Melanin (the chemical that our bodies produce to darken skin tone and hair color) provides protection from UV rays by absorbing them. However, this means that the more melanin that is produced by someone’s body results in less absorption of UV rays and a decrease in Vitamin D production. But for someone living around the equator or in the tropics that doesn’t matter because there’s lots of sun all the time. So for humans living in these areas where there’s lots of sunlight year round, it’s beneficial to have darker skin to protect from the harm of UV rays. People living in these areas still get plenty of Vitamin D though because of that year round sunshine.
Now what about those who’s skin has less melanin, such as those found in the higher latitudes? Well with less sunlight year round, their bodies had to adapt to be able to get enough Vitamin D. So less melanin is produced by the body in order to absorb the lesser amounts of UV rays to make Vitamin D. Lighter skin is, therefore, more beneficial the farther away you go from the tropics.
So essentially:
Pro of Darker Skin tones
-Protection from harmful UV rays
Con of Darker Skin tones
-Less absorption of UV rays and less production of Vitamin D
Pro of Lighter Skin tones
-Greater absorption of UV rays and more Vitamin D production
Con of Lighter Skin tones
-Less protection from harmful UV rays (resulting in sunburns and, in extreme cases, skin cancer)
This is of course the biology answer. The social impacts of different skin tones is a whole different story that you can ask in the history section.
