Answer: Mendel's research lead to several conclusions about the traits and its passing through generations. The two of the conclusion are different forms of a gene account for variation in the inherited traits and some alleles are dominant over others for a given trait.

Explanation

George Mendel was a famous biologist. His research was on genes and traits. His experiment shows how genes gets transferred from parents to offspring. Also he stated about the behavior and dominance and recessive nature of that alleles.

He also gives the possibility of dominance of a trait over other trait. The different forms of gene are responsible for various types of inherited traits in an organism.

Answer:

1) I identified the Golden-Brown Algae.

2)  It was very easy to find the category because of the solid color base and because it only had the daitoms. It did not have multiple like the Green Algae and the Blue-Green Algae.

3) In fresh, brackish or salt water. They are found both in tropical lakes and seas, and in the alpine and polar snows. They are unicellular or multicellular protist plant organisms, whose cells do not form tissues and lack flowers. They are considered the first link in the food chain in the aquatic environment. They are found in fresh, brackish or salt water. They are primary producers in the food chain, capable of producing organic substances through photosynthesis, so they use sunlight. They are found in tropical lakes and seas up to the alpine and polar snows.

4) Producer Alga is A plant and produces food for other organisms.

5) Algae (Euglena) do photosynthesis as plants do. They also move around and eat, as do animals. But they are unicellular. In order to be classified as a plant or animal, an organism has to be multicellular, made of more than one cell. Since it is a unicellular organism with some plant and animal characteristics, it is called a protist. Plant cells have walls while algae does't have one, so it is a protozoan. Algae resemble the protozoa, so they are put into the Protist Kingdom.

Explanation:

I had the project.

Algae recreate a major part of the marine ecosystem because they exist as the decomposers current in the marine ecosystem; any harm to them could cause an inequality in the whole marine ecosystem.

1)The Chrysophyceae, usually named chrysophytes, cryptomonads, golden-brown algae or golden algae exist as an extensive set of algae, seen mainly in freshwater.

2) It stood very easy to see the class because of the solid color base and because it only contained the diatoms. It did not contain multiple like the Green Algae and the Blue-Green Algae.

3) In fresh, saline, or salt water. They exist seen both in tropical lakes and seas and in the alpine and polar snows. They exist as unicellular or multicellular protist plant organisms, whose cells do not constitute tissues and absent flowers. They exist thought the first link in the food chain in the aquatic environment. They exist seen in fresh, brackish, or salt water. They exist as primary producers in the food chain, qualified of producing organic substances through photosynthesis, so they utilize sunlight.

4) Producer Alga exists in a plant and makes food for different organisms.

5) Algae (Euglena) accomplish photosynthesis as plants do. They even move about and eat, as do animals. But they exist unicellular. To be categorized as a plant or animal, an organism contains to be multicellular, made of better than one cell. Since it stands as a unicellular organism with some plant and animal elements, it exists named a protist. Plant cells contain walls while algae don't contain one, so it exists as a protozoan. Algae reach the protozoa, so they stand to put into the Protist Kingdom.

Answer:

The no. of heterozygous carriers = 0.0392

Explanation:

From the given information:

The incidence of this recessive disorder i.e. q² = 1/2500

q² = 0.0004

q = 0.02

From Hardy Weinberg's Equilibrium.

p + q = 1; &

p² + 2pq + q² = 1

∴

p + 0.02 = 1

p = 1 - 0.02

p = 0.98

So, the numbers of heterozygous carrier 2pq is:

= 2 × 0.98 × 0.02

= 0.0392

Answer:

They get energy from food. Autotrophs make their own food through the process of photosynthesis, in which light energy from the sun is changed to chemical energy that is stored in glucose. And as for cellular respiration, all organisms use it to break down glucose, release its energy, and make ATP.

Explanation:

_____________

Answer: We are given:

Mass of solvent (water) = 100 grams

Mass of solute (NaCl) = 20 grams

Mass of the Solution:

Mass of Solution = Mass of Solute + mass of Solvent

100 + 20 = 120 grams

Mass Percent of NaCl:

We know that

mass percent of NaCl = (Mass of NaCl / Mass of Solution) * 100

replacing the variables

Mass% of NaCl = (20 / 120)*100

Mass% of NaCl = 100 / 6

Mass% of NaCl = 16.67%

Explanation:

those are nucleotides

since all three of them contain deoxyribose (because there's only one hydroxil group) they are DNA nucleotides

through protein channel

Transported proteins carry small substances like water, amino acids, and charged ions. One to fifteen angstroms is the range in molecule size that can pass through the membrane. The easier it is for a molecule to move across the cell membrane, the smaller it is.

All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment. A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.

Small molecules or ions can traverse the cell membrane passively without the cell providing any energy. The three basic types of passive transport are osmosis, assisted diffusion, and diffusion.

Gases like oxygen and carbon dioxide, as well as small hydrophobic compounds, quickly traverse membranes. Water and ethanol are examples of small polar molecules that can move across membranes, though more slowly.

Thus, The easier it is for a molecule to move across the cell membrane, the smaller it is.

When a gas obeys Boyle's law, the temperature is held constant. The correct option is C.

Boyle's law is given by Charles Boyle. It is a gas law that states the pressure decrease with the increase in the volume and the temperature remain constant. In other words, the pressure exerted on gas is inversely proportional to the volume of the gas.

The law shows the relationship between pressure and volume, with the temperature remaining constant. There are three gas laws which are given by different scientists. These laws show the relationship between two variables and the third remains constant. These variables are temperature, volume, and pressure.

Thus, the correct option is C. temperature regarding the gas obeys Boyle's law, and it remains constant.

Answer: The answer is A

Explanation:

Society was positively impacted by increased insect control in crops, but it was negatively impacted by harmful chemicals. Hence option A is correct.

DDT is defined as the 1940s saw the development of the first synthetic modern pesticide. It aided in the prevention of illnesses like typhus and malaria. Researchers classify DDT as an endocrine-disrupting chemical, or an EDC, because there is evidence that it alters and disrupts hormones crucial for healthy health, including reproductive health, as well as neurological and immunological processes.

Even while scientists began to raise concerns about such risks in the middle of the 1940s, it wasn't until the publication of Rachel Carson's book Silent Spring in 1962 that the use of the chemical became the subject of broad public concern. DDT, often known as dichlorodiphenyltrichloroethane, is a pesticide used in farming. DDT usage was outlawed in the US in 1972. DDT is still used in several non-American nations to keep mosquitoes that cause malaria at bay.

Thus, society was positively impacted by increased insect control in crops, but it was negatively impacted by harmful chemicals. Hence option A is correct.

One of a pair of chromosomes with the same gene sequence, locations, chromosomal length, and centromere placement is referred to as a homologous chromosome. One paternal and one maternal chromosome make up a homologous pair.

A somatic cell of a human has a total of 46 chromosomes in its nucleus. The father inherits half of them (22 autosomes Plus X or Y chromosome), while the mother inherits the other half (22 autosomes + X chromosome).

A female typically has 23 homologous chromosomes, compared to a male's 22. This is due to the fact that men' X and Y sex chromosomes are not identical. During meiosis, homologous chromosomal pairing is crucial.
