Answer:

Transpiration is the loss of water from a plant in the form of water vapor. Water is absorbed by roots from the soil and transported as a liquid to the leaves via xylem. In the leaves, small pores allow water to escape as a vapor. Of all the water absorbed by plants, less than 5% remains in the plant for growth.

Answer:

A population pyramid is defined as a graphical representation that shows distribution of both genders male and female in all age groups.

The base of a population pyramid represents the birth rate, so a very broad base represents the higher population of younger age children and higher birth rate.

Hence, the wide base shows higher population of younger age children and higher birth rate.

Let's suppose the dominant gene is represented with a capital T and the recessive gene is represented with a lowercase t.

Since recessive genes can only appear when no dominant ones are present, the only possible genotype would be tt.

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).

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.

Among the options provided, animals, plants, and fungi are classified as eukaryotes. Eukaryotes are organisms whose cells contain a well-defined nucleus enclosed by a nuclear membrane and other membrane-bound organelles. They are distinct from prokaryotes, which lack a nucleus and membrane-bound organelles.

Animals are multicellular eukaryotic organisms belonging to the kingdom Animalia. They exhibit a wide range of characteristics and include organisms as diverse as mammals, birds, reptiles, amphibians, fish, and invertebrates. Animal cells are complex and specialized, with various organelles performing specific functions.

Plants, classified under the kingdom Plantae, are also eukaryotic organisms. They encompass a diverse group of organisms ranging from small mosses to large trees. Plant cells have unique features such as cell walls composed of cellulose, chloroplasts for photosynthesis, and specialized structures like roots, stems, and leaves.

Fungi, belonging to the kingdom Fungi, are eukaryotic organisms that include mushrooms, yeasts, molds, and mildews. They exhibit a range of characteristics and can be either unicellular or multicellular. Fungal cells possess a unique cell wall composition, and their mode of nutrition is typically through absorption.

Archaea, on the other hand, are prokaryotic organisms. They constitute one of the three domains of life, alongside bacteria and eukaryotes. Archaea have distinct molecular and genetic characteristics that differentiate them from bacteria and eukaryotes. They are known to inhabit extreme environments such as hot springs and deep-sea hydrothermal vents.

In summary, animals, plants, and fungi are eukaryotes, whereas archaea are prokaryotes. Eukaryotes are characterized by the presence of a nucleus and membrane-bound organelles, while prokaryotes lack these structures.

During dehydration synthesis, water molecule gets removed. The correct option is a.

A dehydration reaction in chemistry is a chemical process in which the reacting molecule or ion loses water. The opposite of a hydration reaction, dehydration reactions are frequent processes.

"Chemical processes known as dehydration reactions are those in which a water molecule is removed from the reactant molecule. Dehydration synthesis is the process of combining two compounds while removing water molecules.

These kinds of reactions can assemble and disassemble nucleic acids, proteins, and carbohydrates, however the monomers in each case vary.

Many polymers are made by dehydration processes as well. Another illustration is the transformation of alcohols into ethers.

Answer:

(A)

Explanation:

can't be flower

can't be color

can't be protective structure

a flower has the ovary which animals have too

Answer:

the answer would be A.

Explanation:

this would be because a cell is the smallest living thing, after cells, tissues are the next smallest thing, then it is an organ, because different tissues make up an organ, then multiple organs will create an organ system, and multiple organ systems create an organism.

The structure of the body has several levels of the organization, and the sequence is cell → tissue → organ → organ system → organism, hence option A is correct.

The human body's biological functions are preserved at several levels of structural organization. The following levels are included: chemical, cellular, tissue, organ, organ system, and organismal.

The lowest unit of life is a cell. A tissue is made up of a variety of unique cells. Organ systems are made up of related organs that are made up of tissues. A living thing or organ is made up of various organ systems.

Therefore,  any organism's cell is its fundamental structural and operative unit. Multicellular organisms are made up of cells, tissues, organs, and organ systems, which are composed of groups of similar cells, tissues, organs, and organ systems.

Answer:

As organisms release energy during cellular respiration, carbon dioxide is produced from the carbon in energy storage molecules. ... Carbon dioxide in the biodome decreased because decomposers decreased which means there was a decrease in cellular respiration overall.

There are several possible reasons why the carbon dioxide levels in the air of a biodome might decrease like photosynthesis, respiration, ventilation and carbon sequestration.

There are several possible reasons why the carbon dioxide levels in the air of a biodome might decrease. Some possible causes include:

Photosynthesis: If the biodome contains plants, they may be using carbon dioxide during photosynthesis to produce oxygen and glucose. This process would remove carbon dioxide from the air.

Respiration: If the biodome contains animals or microorganisms that respire, they may be consuming oxygen and producing carbon dioxide. This would result in a decrease in carbon dioxide levels in the air.

Ventilation: If the biodome has a ventilation system, it may be designed to remove excess carbon dioxide from the air. This could result in a decrease in carbon dioxide levels.

Carbon sequestration: If the biodome has systems in place to capture and store carbon dioxide, such as through the use of plants or other methods, this could result in a decrease in carbon dioxide levels in the air.

It's important to note that the specific cause of a decrease in carbon dioxide levels in the biodome's air will depend on the specific conditions and systems in place within the biodome.

Answer:

independent assortment, crossing over and random fertilization

Explanation:

There are three mechanisms by which sexual reproduction increases genetic variation in progeny. First, random fertilization is the process by which gametes randomly combine in order to increase the possibilities for genetic variation. Second, the independent assortment refers to the process by which pairs of homologous chromosomes independently separate from one another during meiosis. Finally, crossing over, also known as recombination, is the process by which two homologous chromosomes' non-sister chromatids can exchange genetic material during meiosis I (prophase I).
