The diploid cells undergo and produce haploid gametes
Answers
Answer:
The process by which diploid cells undergo and produce haploid gametes is called meiosis.
1. Meiosis is a type of cell division that occurs in the reproductive cells, also known as germ cells.
2. The primary purpose of meiosis is to reduce the chromosome number in half, resulting in the formation of haploid cells.
3. Diploid cells contain two sets of chromosomes, one from each parent, while haploid cells contain only one set of chromosomes.
4. Meiosis consists of two rounds of division, known as meiosis I and meiosis II.
5. During meiosis I, the homologous chromosomes pair up and exchange genetic material in a process called crossing over.
6. This genetic exchange promotes genetic diversity and creates new combinations of genes.
7. After crossing over, the homologous chromosomes separate, resulting in two haploid cells with duplicated chromosomes.
8. Meiosis II is similar to mitosis, where the duplicated chromosomes line up and separate, producing four haploid cells.
9. These four haploid cells are the gametes, such as sperm or egg cells, which are used in sexual reproduction.
10. When two gametes fuse during fertilization, the resulting zygote will have the full diploid chromosome number again.
Overall, meiosis allows for genetic variation and ensures the production of haploid gametes necessary for sexual reproduction.

c. Metabolism is influenced by numerous factors, such as heredity and age.
d. Younger people generally have a slower metabolism than adults.
Answers
Answer;
D. Younger people generally have a slower metabolism than adults.
Explanation;
Basal metabolism is the amount of energy needed for sustaining life. It is the basic, or least, amount of energy the body needs to survive when at rest. It does not include additional energy required to support even a small amount of activity.
Basal metabolism is measured by the amount of calories burned when your body is inactive. Factors, such as, gender, heredity and age influence metabolism of an individual.
Final answer:
The statement, 'Younger people generally have a slower metabolism than adults' is not true. Younger individuals often have a higher metabolism than adults because metabolism usually decreases with age. Metabolism is also influenced by many factors and basal metabolism refers to the energy needed for basic bodily functions.
Explanation:
All the statements about metabolism are true except for:
- d. Younger people generally have a slower metabolism than adults.
The opposite is true. Younger individuals often have a higher metabolism than adults. This is because metabolism often decreases with age due to factors such as a decrease in muscle mass and physical activity.
Metabolism refers to the chemical processes that occur within a living organism in order to maintain life, and it is influenced by numerous factors such as genetics, age, diet, physical activity, and even the environment.
Basal metabolism is the amount of energy (measured in calories) your body needs to maintain basic bodily functions, such as breathing and circulation, when at rest. It accounts for about 60-75% of the calories burned each day.

Answer:
180 mm
Explanation:
We are given that a pencil whose measure 18 cm long .
We have to find that length of pencil in millimeter
In order to find the value of length of pencil in millimeter we are using conversion of centimeter into millimeter by the unitary method
We know that
1 cm =10 mm
Multiply 10 by 18
18 cm =
After multiplying we get
18 cm =180 mm
Length of pencil in millimeter is 180 mm.
Hence, the pencil is 180 mm long.

Answers
In humans, there are two lungs - right and left and each of them is divided into lobes. The left lung has two lobes while the right lung has three lobes.
Speaking of other choices, bronchi conduct air to lungs, and alveoli are places where gas exchange occurs. The capillary is the part of the circulatory system and is connected to alveoli.

Answer:
nervous
Explanation:
The nervous tissue is one of the four basic tissues of the organism, it is formed by two types of cellular elements, it represents the fundamental component of the structures and organs that make up the nervous system. The main function of the nervous tissue is to capture internal and external stimuli and transform them into nerve impulses. All modifications of the external or internal environment and sensory stimuli such as temperature, pressure, light, sounds and taste, among others, are detected, examined and transmitted by nerve cells. On the other hand, the nervous tissue is in charge of coordinating the motor, glandular, and visceral functions of the individual.

Answers
All of the chromosomes are aligned midway between thespindle poles. A spindle is a dynamic network of microtubules thatattaches to and moves chromosomes during nuclear division. Microtubulesattach each chromatid to one of the spindle poles, and its sister to theopposite pole.
Chromosomes attach to spindle fibres by their centromeres during metaphase of mitosis.
Further Explanation:
Interphase is the resting phase or metabolic phase of a cell where it prepares itself for the cell division process. Interphase comprises of sub-phases namely, Gap1 phase, Synthesis phase and Gap2 phase. G1 is the first gap phase where a cell grows larger in size and the cytoplasm volume increases as more organelles are produced. During Synthesis phase, the strands of DNA replicates. G2 is another gap phase in which the cell becomes much larger in size and this phase is followed by mitosis where cell division occurs.
Mitosis or somatic cell division is comprised of four phases which includes prophase, metaphase, anaphase and telophase. A somatic cell divides to give rise to two identical daughter cells where each cell contains exact copy of each chromosomes present in the parent cell. In the prophase, the envelope that covers the nucleus and nucleolus disappears and chromosomes become visible by forming two chromatids attached to centromere.
In the metaphase, chromosomes alignment at the metaphase plate occurs and spindle fibres attach to the centromere. Spindle fibres pull the chromatids away from the metaphase plate towards the opposite poles of the cell during anaphase. In the telophase, nuclear membrane reforms, chromosomes decondense and nuclear membrane reforms around each daughter nuclei. The cytokinesis is the final stage of cell division process where the parent cell is pinched off to result in two daughter cells.
