4) D. What fraction of the male children will be carriers? 07.
5) E. What are the chances of having a child with hemophilia? No sons of a man with hemophilia will have hemophilia. All daughters of a man with hemophilia will be carriers (called obligate carriers). If a carrier has a son, the son has a 50% chance of having hemophilia.
Which of the following is an example of deposition?
a. glaciers wearing down layers of rock b. a muddy river carrying sediment downstream c. ponds filling up with sediment and becoming marshes d. frost wedging splitting rocks apart
Glacial erratics are the name given to these rocks. Erratics serve as a log of a glacier's journey. Complex flow patterns can be discovered by looking for the bedrock units that match with erratics. Thus option A is correct.
What glaciers wearing down layers of rock?The rocks and the ground below are both eroded as a result of the friction caused by glaciers carrying rocks. In this manner, glaciers pulverize rocks and remove dirt. Mountain valleys with steep sides are created by advancing glaciers carving out basins. Moraine, an eroded debris, is frequently seen on and surrounding glaciers.
Mechanical weathering causes the rock on valley walls to become loose as glaciers flow, where it then falls as debris. Rocks of any size, from enormous boulders to silt, can be carried by glaciers. Over many years and decades, these rocks can be transported a great distance.
Therefore, glaciers wearing down layers of rock.

making new organisms
replacing old or damaged cells or tissues
All of the following are functions of asexual reproduction except producing gametes.
What do you mean asexual reproduction?Asexual reproduction is a mode of reproduction in which a new offspring is produced by a single parent. The new individuals produced are genetically and physically identical to each other, i.e., they are the clones of their parents.
Asexual reproduction is a type of reproduction in which only one parent is involved. There are basically 5 types of asexual reproduction. These are binary fission, budding, vegetative reproduction, fragmentation and by spores.
The major disadvantages of asexual reproduction are: Lack of diversity- Since the offsprings are genetically identical to the parent they are more susceptible to the same diseases and nutrient deficiencies as the parent.

Which type of rock is shown in each of these photographs?
In the first image, a sedimentary rock is seen. Sand, mud, and gravel deposits build up over time to produce sedimentary rocks. Typically, these sediments are laid down in layers throughout time, and after being crushed and cemented together, they solidify into rocks.
Due to the variety of sediments that make up sedimentary rocks, these rocks frequently have a layered look. In the second image, an igneous rock is seen. When molten rock, or magma, cools and hardens, igneous rocks are created.
Numerous processes, such as the cooling of lava on the Earth's surface or the crystallisation of magma deep below the Earth's crust, can lead to the formation of these rocks.

A woman bought 10 crates of eggs from the market. On getting home, she realized that 15 eggs were broken. What is the ratio of broken eggs to unbroken eggs.
Answer:
B:U = 1:20
Explanation:
Let the number of broken eggs be B.
Let the number of unbroken eggs be U.
Given the following data;
Number of crates of egg = 10 crates
But, 1 crate of egg = 30 eggs
10 crates of egg = 30 * 10 = 300 eggs
B = 15 eggs
U = 300 eggs
Ratio B to U = B:U
B:U = 15:300
Dividing by 15, we have;
B:U = 1:20

Use your understanding of prevention and treatment of viruses to answer the questions below.
A
is a substance containing incomplete portions of a virus that produce an immune response when injected into the body.
I'm a bit confused about this question. But I will try my best to answer. :)
To prevent a certain virus, or increase someone's immunity towards a virus, doctors give patients a shot/vaccine. For example, people get a flu shot yearly to help prevent them from getting the flu. The shot contains a small portion of the flu itself. The flu remains dormant until the body decides to activate it or fight it off. This also helps the body become more immune to the virus/sickness and fight it off easier.
I hope this helps! :)
A hapten is a substance containing incomplete portions of a virus that produce an immune response when injected into the body.
What is the Immune response?The immune response may be defined as the type of reaction that occurs in response to specific antigens or foreign agents. Such types of responses defend the organism against foreign invaders.
A hapten is essentially an incomplete antigenic particle. Such small substances or molecules only elicit an immune response when attached to a carrier known as proteins.
Carrier molecules typically do not elicit an immune response by themselves.
Therefore, it is well described above.
