Answer:
The four nitrogen bases found in DNA are adenine, cytosine, guanine, and thymine. Each of these bases are often abbreviated a single letter: A (adenine), C (cytosine), G (guanine), T (thymine).
Explanation:
The four nitrogen bases found in DNA are adenine, cytosine, guanine, and thymine. Each of these bases are often abbreviated a single letter: A (adenine), C (cytosine), G (guanine), T (thymine).
What is base-pairing rule?According to the base-pairing rule, the one purine binds with a specific pyrimidine always, the purine adenine (A) only pairs with the pyrimidine thymine (T) and similarly, the purine guanine (G) only pairs with the pyrimidine cytosine (C) in DNA, and in RNA the purine adenine (A) binds with the only uracil.
The bases are Adenine, guanine, guanine, cytosine, thymine, adenine the string of their base pair would be Thymine, cytosine, cytosine, guanine, adenine, thymine.
DNA stands for Deoxyribonucleic acid. It is made up of two complementary strands. There are four nitrogenous base present in the DNA strand. These are-
Adenine (A), thymine (T), guanine (G), and cytosine (C). These bases pair with bases on the complemenatry strand just according to the Watson and Crick base pairing ( A=T, G ≡ C ). Uracil is another nitrogenous base. But it is present in RNA in place of Thymine.
Thus, bases found in the DNA are Adenine, thymine, guanine, cytosine.

All of the following are functions of asexual reproduction except _____.
growth
producing gametes (sex cells)
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.

Which is NOT a function of the stem in plants?
O Store water
O Carry nutrients
O Provide support to the plant
O Anchor the plant in the ground
Answer:
yes D is the answer
Explanation:
cuz steam store water carry nutrients and of course provide support to the plant
Stems are the part of the plant and the structural axes that help in support and transport. The stem does not anchor plants to the ground.
What are stems?Stems are the axis of the plant that bears shoots, leaves, buds, flowers, etc. The stem of the plant conducts water and mineral through the vascular system of the xylem and phloem.
The roots of the plant provide an anchor to the stem. They also store food and water in their structures that are used for further use and make them available at the time of requirement.
The stems are the mechanical structure that provides support to the plant parts and enables them to stand upright.
Therefore, option D. anchor to the ground is not provided by the stem.

_______________ and ________________________________ factors can affect an organism’s traits.
Answer: Genetic makeup and environment
Explanation:
Genetic makeup of an organism is dependent upon the genes inherited from the parents. The genes when express are responsible for the development of specific traits in an organism. The environment is also responsible for contributing to the development of traits in an organism. For example, an organism is able to tolerate the cold environmental conditions and can survive in cold habitat as it has inherited traits from the parents but when exposed to hot environmental conditions then it will adapt to the changes in the environment due to development of heat tolerant trait. Also a person has inherited traits of short height from parents but when provided with nutritious food and performs regular physical activities the person had attained tallness due to environmental factors.

Light and chlorophyll are necessary for plants to photosynthesise. Photosynthesis is when plants use sunlight and carbon dioxide to make glucose. But chlorophyll is required to make this happen. It's important that plants make their own food so they don't die, since plants are the number one source of oxygen.
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.

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.

Answer:
A i think lol
During replication, DNA unwinds into two distinct strands, with each strand producing a perfect duplicate of the other. A DNA strand is utilized during translation to create a corresponding strand of mRNA with uracil replacing thymine. Hence option A is correct.
What is replication of DNA?Replication of DNA is defined as the biological process of splitting a single DNA molecule into two identical copies. A double-stranded DNA molecule is copied to create two identical DNA molecules during the DNA replication process. The three primary stages of replication are priming of the template strand, building of the new DNA segment, and opening of the double helix and separation of the DNA strands.
All biological cells contain it, and even though its synthesis takes place in the nucleus, it typically occurs in the cytoplasm of the cell. While DNA provides the instructions for the actions of the cell, RNA is in charge of translating those instructions into proteins that perform diverse cellular tasks.
Thus, during replication, DNA unwinds into two distinct strands, with each strand producing a perfect duplicate of the other. A DNA strand is utilized during translation to create a corresponding strand of mRNA with uracil replacing thymine. Hence option A is correct.

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
