Answer:

Plants have two distinct stages in their lifecycle: the gametophyte stage and the sporophyte stage. After reaching maturity, the diploid sporophyte produces spores by meiosis, which in turn divide by mitosis to produce the haploid gametophyte. The new gametophyte produces gametes, and the cycle continues.

Explanation:

Answer:

plants have multicellular haploid and multicellular diploid stages in their life cycle. Gametes develop in the multicellular haploid gametophyte (from the Greek phyton, “plant”). Fertilization gives rise to a multicellular diploid sporophyte, which produces haploid spores via meiosis.

Answer:

In cellular respiration, complex molecules containing carbon react with oxygen to produce carbon dioxide and other materials. Within individual organisms, food moves through a series of chemical reactions in which it is broken down and rearranged to form new molecules to support growth or to release energy.

Explanation:

The glucose and oxygen atoms are rearranged into carbon dioxide and water molecules during aerobic respiration. Being an exothermic chemical reaction, this process releases energy as it goes along.

A chemical reaction that converts carbohydrates into energy using oxygen (sugars). also known as oxidative metabolism, aerobic metabolism, and cell respiration.

During aerobic cellular respiration, glucose and oxygen combine to create ATP, which the cell can utilise.

As byproducts, carbon dioxide and water are produced. The general equation for aerobic cellular respiration is: ATP is produced when glucose and oxygen combine in cellular respiration.

During aerobic respiration, glucose and oxygen atoms are rearranged into carbon dioxide and water molecules. As it proceeds, this process releases energy since it is an exothermic chemical reaction.

Thus, molecules of food rearrange when they react with oxygen in the cells of your body.

Explanation:

mitosis creates exact copies of the starting cell

In mitosis the two resulting cells are identical to the starting cell and identical to each other. Therefore, option (D) is correct.

In cell biology, the cell cycle phase known as mitosis is when replicated chromosomes are divided into two new nuclei. Mitosis, the process of cell division, creates genetically identical cells with a constant number of chromosomes. Thus, equational division is another name for mitosis.

Making additional diploid cells is the goal of mitosis. Each chromosome is copied, and the copies are then distributed to the various sides of the cell. In this method, each new cell receives a copy of each chromosome when the cell splits in half.

Answer:

Karotyping is a chromosomal analysis. It can be used to look for diseases caused by irregularities in the chromosomes, such as Down syndrome.

Explanation:

Karotyping is a chromosomal analysis of the chromosomal constitution of the nucleus of a cell, which is equal to the complete chromosomal makeup of a person. The chromosomes of each species have a certain structure both in size, shape and their own band when they are stained in the laboratory. This allows them to be identified as well as to know if all the genetic information is in the correct order. In addition to numerical abnormalities in chromosomes, structural alterations mean that certain chromosomal regions can be duplicated or even absent. This gain or loss of genetic material has highly varied consequences depending on the genes involved. Another type of structural alterations are translocations and inversions. The karyotype can be studied in search of diseases caused by irregularities in the chromosomes, such as Down syndrome. It also helps to identify problems that a baby conceived through assisted reproduction may have when it is born, by extracting the karyotype that is found in the amniotic fluid of the embryo.

Water as a Compound and Molecule

A compound forms whenever two or more atoms form chemical bonds with each other. The chemical formula for water is H2O, which means each molecule of water consists of one oxygen atom chemically bonded to two hydrogen atoms. Thus, water is a compound. It's also a molecule, which is any chemical species formed by two or more atoms chemically bonded to each other. The terms "molecule" and "compound" mean the same thing and can be used interchangeably.

Sometimes confusion arises because the definitions of molecule and compound haven't always been so clear-cut. In the past, some schools taught that molecules consisted of atoms bonded via covalent chemical bonds, while compounds were formed via ionic bonds. The hydrogen and oxygen atoms in water are covalently bonded, so under these older definitions, water would be a molecule but not a compound. An example of a compound would be table salt, NaCl. However, as scientists came to understand chemical bonding better, the line between ionic and covalent bonds became fuzzier.

Answer: water is a polar molecule

Explanation: water H2O has two covalent bonds between Oxygen and Hydrogen atoms. Both are non-metals and share outer electrons for forming a covalent bond.

Oxygen has much greater electronegativity and it pulls shared electrons with greater force. So bond is polar and because molecule is V-shaped, Oxygen has permanent

Negative partial charge. Also molecule is polar and makes Hydrogen bonds with other water molecules.

the largest of all the ecosystems, oceans are very large bodies of water that dominate the Earth's surface. Like ponds and lakes, the ocean regions are separated into separate zones: intertidal, pelagic, abyssal, and benthic. All four zones have a great diversity of species. Some say that the ocean contains the richest diversity of species even though it contains fewer species than there are on land. The intertidal zone is where the ocean meets the land — sometimes it is submerged and at other times exposed, as waves and

B. reduces the amount of water vapor

Explanation:

Tropical rainforests is an area of vegetation comprising of predominantly trees. Trees play a major part in sustaining the environment, and hence, the destruction of trees will result in certain negative effects or impacts on the environment.

One of the effects of destroying rainforests according to the options in the question, is the reduction in the amount of water vapor. Trees in rainforests contribute to the addition of water vapor to the atmosphere via transpiration (loss of water through their stomata). Hence, destruction of tropical rain forests will reduce the amount of water vapor.

Explanation: The four daughter cells resulting from meiosis are haploid and genetically distinct. The daughter cells resulting from mitosis are diploid and identical to the parent cell.

The main differences between mitosis and meiosis occur in meiosis stage I.

For the most part, in mitosis, diploid cells are partitioned into two new diploid cells, while in meiosis, diploid cells are partitioned into four new haploid cells.

In mitosis, the daughter cells have the same number of chromosomes as the parent cell, while in meiosis, the daughter cells have half the number of chromosomes as the parent.

The daughter cells produced by mitosis are identical, whereas the daughter cells produced by meiosis are different because crossing over has occurred.

The events that occur in meiosis but not mitosis include homologous chromosomes pairing up, crossing over, and lining up along the metaphase plate in tetrads.

Meiosis II and mitosis are not reduction division like meiosis I because the number of chromosomes remains the same; therefore, meiosis II is referred to as equatorial division.

When the homologous chromosomes separate and move to opposite poles during meiosis I, the diploid level is reduced from two to one, which is referred to as a reduction division.

TWO features of meiosis are recombination and independent segregation.

In conclusion, TWO features of meiosis are recombination and independent segregation.
