Answer: Sequence will be AGCAT.
Explanation:
DNA replication, as used in molecular biology, is the biological process that creates two identical copies of DNA from a single original DNA molecule. Its mechanism is different in eukaryotes and prokaryotes.
The DNA sequence that is duplicated when mRNA is produced is referred to as a template strand. It refers to the strand that is utilized by the enzymes responsible for DNA replication or RNA transcription to attach complementary nucleotides.
DNA polymerases, which require a template and a primer (beginning) and synthesis DNA in the 5' to 3' orientation, are the enzymes responsible for creating new DNA. One new strand (the leading strand) is created during DNA replication in one continuous piece. Small fragments make up the other (lagging strand).
So, According to the Chargaff's Rule and Complementary bases. A pairs with T and G with C.

How does the plasma membrane contribute to the structure and function of the cell
Answer:
It contributes to the structure and function because it is a thin membrane that surrounds the cell and controls what goes in and out of it.
Explanation:
Compare mitosis and meiosis in the following two attributes:
- the number of copies of DNA and whether the copies are different
-what kinds of cells undergo these two processes
Thank you!
Mitosis may be defined as a type of cell division in which a parental cell is divided into two daughter cells that are genetically identical to them. These daughter cells are diploid in nature. Somatic cells of the body undergo this process of cell division.
What is Meiosis?Meiosis may be defined as a type of cell division in which a parental cell is divided into four daughter cells that are genetically unique to them. These daughter cells are haploid in nature. Germ cells (gamete cells) of the body undergo this process of cell division.

The reaction satisfies the Law of Conservation of Matter because the number of each type of atom is the same in the products and reactants.
The above given statement is true.
What is the "Law of Conservation of Matter"?
The "Law of Conservation of Matter" states that "matter can neither be created nor be destroyed". In other words, the total mass of an isolated system remains constant over time, as mass is neither created nor destroyed. This law applies to all types of matter, including atoms, molecules, and energy.
What are Atoms?
Atoms are basically the basic building blocks of matter. They are composed of protons, neutrons, and electrons and are the smallest particle of an element that still retains the properties of that element. Atoms are the fundamental units of chemistry and form the basis of all matter in the universe.

The correct strand of RNA bases is UGGCUCGAA. Therefore, the correct option is B.
What is a nucleotide?RNA is a nucleic acid that is composed of nucleotides. A nucleotide is composed of a sugar molecule, a phosphate group, and a nitrogenous base. RNA differs from DNA in its single-stranded structure, the presence of uracil instead of thymine, and the sugar molecule being ribose.
The sequence of bases determines the genetic information in RNA. The bases in RNA are adenine, cytosine, guanine, and uracil. The sequence UGGCUCGAA represents an RNA sequence of bases.
The sequence UGGCUCGAA transfers the genetic information from the DNA to ribosomes, where the sequence is translated by ribosomes into amino acids, which results in the formation of a specific protein with a unique function in the cell.
Therefore, the correct strand of RNA bases is UGGCUCGAA.

The picture below shows flowers on a tomato plant.
Lacy wants to design an experiment that will show which part of a tomato flower grows into the tomato fruit. What measurement could she make to study how the fruit grows?
Lacy wants to design an experiment that will show ovary part of a tomato flower grows into the tomato fruit.
What is ovary for plant?The female reproductive organ present in flowering plants is the ovary. It is present in the flower's gynoecium. It is a portion of the pistil that holds the ovules and is located near the base of the sepals and petals. A single carpel or numerous carpels joined together can form the pistil.
Ovaries, as we know, are an essential component of the plant's female reproductive system. Well, the ovaries are where pollen is kept before developing into ovules and ultimately seeds. These seeds then germinate, causing the ovaries to grow and convert into fruits.
Even though the blooms are self-fertile, the pollen is nevertheless moved to the female half of the blossom by wind and the buzzing of bees' wings. The young tomato grows after fertilization, when the petals and stamens fall off.
So, Lacy will show ovary part of a tomato flower grows into the tomato fruit.

An antelope population has a negative population growth rate. Which of the following conditions must also be true for the population growth rate to be negative?
a. births + deaths < immigrations + emigrations
b. births + deaths > immigrations + emigrations
c. births + immigrations < deaths + emigrations
d. births + immigrations > deaths + emigrations
The antelope population has a negative population growth rate. So, the birth rate + immigration rate of the population will be less than the death rate and emigration rate. Thus, the correct option is C.
What is Population growth rate?Population growth rate is the increase or decrease in the number of individuals in a population or a dispersed group. Population growth depends upon several factors which include:
1. Birth rate: It is the total number of new births in a population. It increases the population growth.
2. Death rate: It is the total number of deaths in a population. It decreases the population growth.
3. Immigration: It is the entry of new individuals through migration into a population. It increases the population growth.
4. Emigration: It is the removal or migration of individuals from a population. It decreases the population growth.
Thus, a population with negative population growth rate will have birth rate and immigration less than the death rate and emigration rate.

why carbohydrate digestion occurs first in mouth?
The digestion of starch carbohydrate is initiated in mouth due to the action of starch digesting enzyme ptyalin or salivary amylase present in saliva secreted by salivary glands. Enzymatic hydrolysis helps in the partial breakdown of starch (polysaccharide) into maltose and isomaltose (disaccharides) and small dextrins called 'limit' dextrins. Nearly 30% of the starch is hydrolysed in the oral cavity because of the shorter time the food is retained here

Select three events that occur as an unspecialized cell differentiates into a cell that helps transport water in plants.
Answer:
Explanation:
Differentiation dramatically changes a cell's size, shape, membrane potential, metabolic activity, and responsiveness to signals. These changes are largely due to highly controlled modifications in gene expression and are the study of epigenetics.
The three events that occur as an unspecialized cell differentiates into a cell that helps transport water in plants are as follows:
Formation of vascular bundles like xylem and phloem.Cells are adapted to perform the process of photosynthesis and transpiration.Cells of the plant tissue become more compact than usual. What is cell differentiation?Cell differentiation may be defined as the process during which young, immature (unspecialized) cells take on individual characteristics and reach their mature (specialized) form and function.
In order for a cell to differentiate into its specialized form and function, it need only to manipulate those genes (and thus those proteins) that will be expressed, and not those that will remain silent. The primary mechanism by which genes are turned “on” or “off” is through transcription factors.
Therefore, the three events that occur as an unspecialized cell differentiates into a cell that helps transport water in plants are well-described above.

Why is the femur of a whale considered to
be a vestigial structure?
It no longer serves a function in the animal. This is the answer
It is the most useful structure in the animal.
Answer: Because whale swims and femur is not required in this.
Explanation:
Sometimes, parts of the body that were useful to our ancestors no longer are in our bodies. These structures, like the pelvis and femur in whales, are proof that natural selection over time allowed us to evolve from ancestors who possessed different characteristics.
Whales' femur and pelvis are regarded as vestigial structures. These buildings were passed down from relatives who used them, but they are no longer in use. Animals that once walked on land have given rise to whales.
For this reason, their forebears need a pelvis and femur bones. Whales have these structures today, but they did not develop the ability to swim, despite the fact that they do.
