Why KOH solution is kept in the test tube inside the air tight conical flask while doing the experiment of respiration of seeds?
Answer:
It is kept inside to absorb the CO2 released by the germinating seeds.
Explanation:
It means it will create a cycle for the flask. So, an equal volume of water rises up in the tube.

What is the atom structure?
Answer:
The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged). Atoms have different properties based on the arrangement and number of their basic particles.

Explanation:
in the term 2pq of the Hardy-Weinberg equation. Why is the multiplication by two necessary?
PLEASE HELP ME!!!!!
A-The term is multiplied by two because the effect of both the alleles is taken into account.
B-There are two ways that a heterozygous individual can arise: either by receiving a recessive allele from the egg and a dominant allele from the sperm, or by receiving a dominant allele from the egg and a recessive allele from the sperm
C-The frequency of the dominant allele is doubled because of its stronger effect on the phenotype.
D-The term is multiplied by tvo to account for doubling of the population in each generation.
Answer:
The correct answer is : option B.
Explanation:
Hardy–Weinberg equilibrium is a mathematical model that states that genotype percentage or frequency in a population and allele in a population remains stable or constant to generations if there are no evolutionary influences present.
Hardy Weinberg equation is :
P²+2pq+q² = 1
Here, p² represents the frequency of genotypes dominant homozygotes (AA) in a population in equilibrium. The term 2pq represents the frequency of heterozygotes (Aa) as there are two ways of developing heterozygous individuals either dominant from the egg and recessive from sperm or vice versa. and the term q² represents the frequency of recessive homozygotes (aa).
Thus, the correct answer is : option B.
There are two ways that a heterozygous individual can arise: either by receiving a recessive allele from the egg and a dominant allele from the sperm, or by receiving a dominant allele from the egg and a recessive allele from the sperm, the frequency of the heterozygous allele is multiplied by 2 (option B).
The Hardy–Weinberg equation is an equation which expresses the principle of Hardy-Weinberg equilibrium. The Hardy-Weinberg equilibrium states that in the absence of external evolutionary factors which disturbs equilibrium, the amount of genetic variation in a population will remain constant from one generation to the next.
The Hardy Weinberg equation is given as: p² + 2pq + q² = 1
In the equation above,
p² represents the frequency of dominant h0m0zygotes (AA)q²represents the frequency of recessive h0m0zygotes (aa),2pq represents the frequency of heterozygotes (Aa),p represents the allele frequency of the allele A and q represents the allele frequency of the allele a.The sum of all the three frequencies equal to 1 representing all the possible allele combinations.Since there are two ways that a heterozygous individual can arise: either by receiving a recessive allele from the egg and a dominant allele from the sperm, or by receiving a dominant allele from the egg and a recessive allele from the sperm, the frequency of the heterozygous allele is multiplied by 2.

i am generally found both inside and outside of the nucleus {in eukaryotic cells} is it DNA O RNA ?
Answer: RNA
Explanation:
Nearly all the RNA found in a typical eukaryotic cell is rRNA. Transfer-messenger RNA (tmRNA) is found in many bacteria and plastids.
What is generally found both inside and outside of the nucleus of a eukaryotic cell is ; RNA
RNA is formed in eukaryotic cells when DNA contained in the nucleus of the cell is transcribed/synthesized. The transcribed RNA is then moved out of the nucleus into the cytoplasm.
The RNA contained in the cytoplasm is later transcribed into protein in the cytoplasm of the cells . therefore RNA is contained both inside and outside the nucleus of a eukaryotic cell.
Hence we can conclude that what is generally found inside and outside the nucleus of a eukaryotic cell is RNA

what animals that grow naturally in the Pacific Northwest and Kitsap Peninsula ? please help
Answer: Pacific Northwest Animals & Birds
Spotted and snowy owls. Bald and Golden eagles. Pileated woodpecker. Rufous hummingbird. Great Blue Heron and Canada goose. Seabirds, including cormorant. Bear. Olympic marmot.Kitsap Peninsula:
Marine mammals of the sound include orcas, sea lions, sea otters, gray whales, humpback whales, and harbor seals. Underwater plants provide food, breeding areas, nurseries, and resting places for wildlife in the sound.
Mammals that live in the Arctic Ocean have a large amount of blubber, which is a fatty tissue just beneath the skin.
Which statement best relates why these animals have so much blubber?
O Lipids in blubber insulate the animals from cold water.
O Proteins in blubber help the animals move to stay warm.
O Carbohydrates in blubber provide all the energy that the animals need to stay warm.
O Nucleic acids help build the lipids in blubber, which keep animals warm by regulating cell activities.
Answer:
Lipids in blubber insulate the animals from cold water.
Explanation:
Lipids are fatty tissue, or fats in the cells. Blubber is fat. The fat helps insulate animals from cold water, especially in the Arctic known for being freezing. Fats can help maintain and keep body heat, hence why skinnier people are colder. Without lipids, they would most likely freeze.

Lipids

A scientist has discovered a new plant species in the Amazon rainforest she tells her fellow scientist at the Playhouse she has found for Tuesday is a cone for my side about this plan is different from an organism
Answer:
It is a seeded vascular plant.
It does not depend on insect pollination.
Explanation:
The complete question is: A scientist has discovered a new plant species in the Amazon rainforest. She tells her fellow scientists that the plant she has found produces a cone. What might they say about how this plant is different from an angiosperm? Its seeds have one or two cotyledons. Its stems' vascular bundles are scattered. It does not depend on insect pollination. It is a seeded vascular plant.
The correct option would be that the plant is a seeded vascular plant and does not depend on insect pollination.
Gymnosperms are the only group of plants that produce cones. They are one of the plant groups that have vascular tissues in the form of xylem and phloem as well as been able to produce seed in the form fo cones. Hence, they are said to be seeded vascular plants.
Gymnosperms also carry out their pollination by relying solely on wind for the transfer of their pollen grain to the female organ. In other words, they do not depend on insect for pollination.
