Solar radiation that is not reflected back into the atmosphere cause the earth's temperature will increase.

Solar radiation is energy emitted from the thermonuclear part that occurs in the sun. Some of the sunlight that enters the earth will be absorbed by the earth and some will be released into the atmosphere outside the earth. However, because there are greenhouse gases in the atmosphere, radiation cannot leave the earth and is trapped in the earth and causes the earth's temperature to increase.

Global warming is an increase in the average temperature of the atmosphere, sea and land on earth. This increase in temperature occurs due to the trapping of radiation by the increased concentration of greenhouse gases in the atmosphere. This increase in temperature causes a variety of negative impacts such as uncertain climate and melting of ice at the poles, causing sea levels to rise. The rising temperature of the earth also causes drought in many places.

1. Gametes - A. sex cells: Gametes are specialized cells involved in sexual reproduction. They are either sperm cells (male gametes) or egg cells (female gametes). Gametes contain half the number of chromosomes compared to somatic cells and combine during fertilization to form a zygote with a complete set of chromosomes.

2. Gametogenesis - I. process by which gametes, or sex cells, are produced by an organism: Gametogenesis is the process through which gametes are formed. It involves the development and maturation of germ cells in the gonads (testes in males, ovaries in females) into functional gametes. In males, the process is called spermatogenesis, resulting in the production of sperm cells, while in females, it is called oogenesis, resulting in the production of egg cells.

3. Genetic recombination - G. exchange of genetic material between different organisms: Genetic recombination refers to the exchange of genetic material between homologous chromosomes during meiosis. It leads to the creation of new combinations of genes, promoting genetic diversity. This process occurs through crossing over, where segments of chromosomes swap places, and contributes to the uniqueness of offspring.

4. Gonad - B. testes and ovary: The gonads are reproductive organs responsible for producing gametes. In males, the gonads are the testes, which produce sperm cells. In females, the gonads are the ovaries, which produce egg cells. The gonads also secrete hormones involved in sexual development and reproduction.

5. Haploid - D. single set of unpaired chromosomes: Haploid refers to a cell or organism having a single set of unpaired chromosomes. Gametes are haploid cells, containing half the number of chromosomes found in somatic cells. During fertilization, haploid gametes combine to restore the diploid chromosome number in the resulting zygote.

6. Importance of meiosis - K. ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes by producing haploid gametes: Meiosis is vital for sexual reproduction as it ensures the correct number of chromosomes in offspring. By undergoing two rounds of division, meiosis produces haploid gametes with a single set of chromosomes. When fertilization occurs, the fusion of two haploid gametes forms a diploid zygote with the right chromosome number for the species. Meiosis also promotes genetic diversity through genetic recombination, contributing to evolutionary adaptation.

7. Oogonium - E. The immature female reproductive cells: Oogonium refers to the immature female reproductive cells found in the ovaries. These cells undergo mitotic divisions to produce primary oocytes, which later undergo oogenesis to form mature egg cells (ova).

8. Ovulation - C. the release of eggs from the ovary: Ovulation is the process in which a mature egg cell (ovum) is released from the ovary. In females, ovulation typically occurs once per menstrual cycle, and it is an essential step in fertility and reproduction.

9. Extra fingers - H. common physical characteristics of people with Patau syndrome: Extra fingers, or polydactyly, refers to the presence of more than the usual number of fingers or toes. However, in the given options, there is no direct correspondence to this term.

10. 47, XXY syndrome - J. an illness in the sex chromosome among males which is also identified as Klinefelter Syndrome: 47, XXY syndrome, also known as Klinefelter Syndrome, is a chromosomal disorder that affects males.

Answer:

During exercise, your body may need three or four times your normal cardiac output, because your muscles need more oxygen when you exert yourself. During exercise, your heart typically beats faster so that more blood gets out to your body.

Explanation:

During exercise, the "body's oxygen demands increase as muscles require more energy to contract and perform work".

To meet this increased demand for oxygen, the body must increase the rate and volume of blood flow to the muscles.

The heart, which is responsible for pumping blood throughout the body, responds to this increased demand by increasing its rate of contraction and pumping more blood with each beat.

The heart rate is controlled by a specialized group of cells in the heart called the sinoatrial (SA) node, which acts as the heart's natural pacemaker. The SA node generates electrical impulses that travel through the heart and causes it to contract.

During exercise, signals from the sympathetic nervous system increase the activity of the SA node, causing it to generate electrical impulses more frequently and increase the heart rate.

In addition to increasing the heart rate, the sympathetic nervous system also causes the heart to contract more forcefully, which increases the volume of blood pumped with each beat.

Together, these responses help to deliver more oxygen and nutrients to the muscles during exercise and remove waste products such as carbon dioxide more efficiently.

Answer:

The water is transported to the top most leaves (and rest of its parts) of a tall tree by three actions:

1) root pressure (osmosis)

2) capillary action (adhesion)

3) evapotranspiration (cohesion)

Explanation:

The trees contain a series of interconnected tissues (xylem and phloem) that act as network for transport of water and nutrients throughout the tree. The root pressure and capillary action push the water, while the transpiration from the leaves pull the water. The root pressure is generated by osmotic movement of water from soil to the root tissues. The capillary action is caused due to adhesion of water molecules. However, root pressure and capillarity is thought to support only few meters of water column. The rest of the water transport (esp. in tall trees) is attributed to negative pressure generated by evaporation of water from leaves. This negative pressure creates a vacuum and pulls the water from the roots.

Littoral zones are more likely to contain vegetation than riparian zones. This statement is TRUE.

Littoral zone: This is the region of a body of water close to the shore. The littoral zone is the area of the lake where the rooted plants are able to grow. It is the area of the lake where sunlight penetrates all the way to the sediment and allows aquatic plants to grow. Therefore, the littoral zone is more likely to contain vegetation than riparian zones. Riparian zone: This is the area adjacent to a stream or river. Riparian zones are unique and provide a diverse range of habitats for different species. The vegetation in this zone is very important for the proper functioning of stream and river ecosystems. While it may contain vegetation, the likelihood is lower than that of the littoral zone.

If a hydrophilic amino acid on the surface of an enzyme were changed to a hydrophobic amino acid, then the folding pattern of the enzyme's polypeptide chain would change. The correct answer is option E.

When a hydrophilic amino acid on the surface of an enzyme is changed to a hydrophobic amino acid, it can result in a change in the folding pattern of the enzyme's polypeptide chain. This is because hydrophilic amino acids are attracted to water and tend to be on the surface of the protein.

While hydrophobic amino acids tend to be buried within the protein's interior. Changing the amino acid can disrupt the interactions between the amino acids and the surrounding water molecules, which can lead to a change in the protein's folding pattern. This can affect the enzyme's tertiary structure and potentially its function as well.

The iris diaphragm and condenser are important components in a microscope that control the amount of light reaching the specimen, and adjusting them ensures a clear and well-lit image.

A microscope is a tool used to observe specimens in detail, and to do so, it is important to have proper lighting.

The iris diaphragm and condenser are two components in a microscope that control the amount of light reaching the specimen. The iris diaphragm is a adjustable opening in the light path that regulates the amount of light that enters the microscope, while the condenser focuses the light onto the specimen.

By adjusting the iris diaphragm, the amount of light entering the microscope can be controlled, making it easier to view delicate specimens that might be damaged by too much light. The condenser, on the other hand, focuses the light onto the specimen, providing a bright and well-lit image, which is crucial for viewing details.

The correct answer is d. they share an ancestor. When two animals have an identical sequence of amino acids in a protein, it suggests they share a common ancestor with a conserved genetic information.

When two animals have an identical sequence of amino acids in one of the proteins found in their cells, it indicates that they share a common ancestor. Proteins are encoded by genes, and the sequence of amino acids in a protein is determined by the DNA sequence of the corresponding gene. The DNA sequence is passed down from generation to generation through inheritance.

If two animals have the same sequence of amino acids in a specific protein, it suggests that the DNA sequence coding for that protein has been conserved over time, likely due to a shared ancestry. This conservation of the protein sequence indicates that the genetic information for producing that protein has been passed down from a common ancestor to both species.

On the other hand, options a, b, and c are not necessarily true based solely on the fact that two animals have an identical sequence of amino acids in a protein. The animals could have different dietary habits (option a), may have been exposed to different mutagenic substances (option b), and do not necessarily belong to the same genus (option c). Only the shared ancestry (option d) is directly indicated by the identical protein sequence.
