Answer:

By sex in eukaryotes, we understand a more-or-less regular succession of meiosis and syngamy. A natural consequence of this is the alternation of haploid and diploid phases in the life cycle. Eukaryotic sex significantly differs from prokaryotic sex in two crucial respects: the cellular mechanisms are quite different, and the transfer of genetic material in prokaryotes is less frequent and more localized (Maynard Smith et al., 1991). However, there seems to be significant continuity in the molecular mechanisms: sex in either case requires recombination enzymes, many of which are active in repair of damaged DNA as well. Thus, it seems plausible that recombinational repair was a preadaptation for sexual recombination. We mention in passing that there is a theory that selection for the recombinational repair of doublestrand DNA damage is responsible for the current maintenance of eukaryotic sex (Bernstein et al., 1981, 1988), but there are severe theoretical as well as factual problems with this theory; we will mention some factual difficulties later. Although an alternation of haploid and diploid phases follows from sex, a clue to the origin problem may lie in the idea that this alternation existed before the evolution of sexual recombination proper. The first hint that this may have been so comes from the classic paper by Cleveland (1947), where he proposed that the haploid-diploid cycle may have started with a spontaneous diploidization by endomitosis: that is, without syngamy. His suggestions were based on original observations on primitive flagellates (hypermastigotes and polymastigotes). Among them, Barbulanympha has a regular endomitosis-meiosis cycle. Margulis & Sagan (1986) called renewed attention to Cleveland’s ideas. In particular, they argued that the alternation of ploidy phases could have a primarily ecological explanation: if the environment alternates in some important factors, this may drive a haploid-diploid cycle, provided the phases are adaptations to different environments. For example, diploids have a smaller relative surface area than haploids, which may confer higher metabolic efficiency. We shall come back to such ideas soon. We focus first on the possible cellular mechanisms connecting the two phases. It is important that some protists have a one-step rather than a two-step meiosis: after syngamy, the two homologous chromosomes become disjunct without premeiotic doubling.

In order to prepare human explorers for travel past low Earth orbit, the  International Space Station (ISS) will be used as a venue for experimentation on tasks including developing safeguards versus space radiation and studying the long-term impacts of reduced gravity.

The aerospace companies of Russia, the United States, Europe, Japan, and Canada cooperatively manage the International Space Station (ISS). Since the outpost's first component was sent into orbit in 1998, it has been continually inhabited for almost 22 years. It is used to test out equipment for upcoming space missions and perform science research in zero gravity. It is now possible for astronauts to remain in space permanently thanks to theInternational Space Station (ISS). Since the first crew's departure, people have been residing in space every day. Crew members are able to perform in the International Space Station (ISS)'s laboratories. Incredibly, the space station will have been in orbit for 21 years as of 2022. The International Space Station (ISS) is far past its projected decommissioning deadline of 15 years, as NASA and its collaborators had anticipated.

Answer:

the answer is option c cellulose..

Explanation:

Cellulose is a molecule, consisting of hundreds – and sometimes even thousands – of carbon, hydrogen and oxygen atoms. Cellulose is the main substance in the walls of plant cells, helping plants to remain stiff and upright. Humans cannot digest cellulose, but it is important in the diet as fibre.

Starch or amylum is a polymeric carbohydrate consisting of numerous glucose units joined by glycosidic bonds. This polysaccharide is produced by most green plants as energy storage

Glycogen is a multibranched polysaccharide of glucose that serves as a form of energy storage in animals, fungi, and bacteria. The polysaccharide structure represents the main storage form of glucose in the body.

hope it helped you and the answer is correct

The term that is used for structure and not for energy is cellulose, which is difficult to break apart. The correct option is c.

A molecule called cellulose is made up of hundreds, and occasionally even thousands, of carbon, hydrogen, and oxygen atoms. The primary component of plant cell walls, cellulose, keeps plants rigid and upright.

A polymeric carbohydrate known as starch or amylum is made up of many glucose units connected by glycosidic linkages. Most green plants synthesize this polysaccharide as a form of energy storage.

Animals, fungi, and bacteria all use the multibranched polysaccharide of glucose known as glycogen to store energy. The primary form of glucose storage in the body is represented by the polysaccharide structure.

Therefore, the correct option is C) cellulose, which is difficult to break apart.

The phenotype ratio for the offspring of heterozygous parents are 3:1.

Phenotype ratio is a ratio that describes the relative number of individuals in a population that display a particular observable trait or phenotype. In genetics, phenotype ratio is often used to describe the outcomes of genetic crosses or experiments.

For example, in a simple dominant-recessive inheritance pattern, a cross between two heterozygous individuals (Aa x Aa) will result in a 3:1 phenotype ratio, with three individuals showing the dominant trait (AA or Aa) and one individual showing the recessive trait (aa). Phenotype ratios can vary depending on the genetic traits involved and the environmental factors that affect their expression.

Answer:

Explanation:

Cancerous growth: Uncontrolled cell division can lead to the formation of a mass of abnormal cells called a tumor. The tumor can continue to grow and invade nearby tissues, leading to cancer. Cancer cells grow and divide without proper regulation, and they can also evade the immune system and resist cell death signals.

Cellular stress: Cells have a limited capacity to grow and divide, and if they do so excessively, they may experience stress due to an overload of cellular processes. For example, the cell may need to produce more energy, replicate its DNA, and synthesize proteins to support the growing cell population. If the cell cannot cope with this stress, it may undergo cell death or senescence, a state where the cell stops dividing but remains metabolically active.

Organ dysfunction: If abnormal cells continue to replicate and grow, they may form masses that can impair the function of organs. For example, a tumor in the brain can put pressure on surrounding tissues and interfere with cognitive function. Similarly, a tumor in the lungs can block air passages and impair breathing.

Mutation accumulation: As cells continue to replicate without proper regulation, mutations in their DNA can accumulate, increasing the risk of cancer development. The accumulation of mutations can result from errors in DNA replication, exposure to environmental toxins, or defects in DNA repair mechanisms. Over time, these mutations can affect critical genes that regulate cell growth and division, leading to uncontrolled cell proliferation.

Cell death: In some cases, uncontrolled cell division may result in cell death due to excessive stress or a lack of essential nutrients. For example, if the cell population grows faster than the available nutrients, cells may compete for limited resources, leading to nutrient deprivation and cell death. Similarly, if the cell population exceeds the capacity of the surrounding tissue to support it, cells may undergo programmed cell death, or apoptosis, to prevent damage to nearby tissues.

microorganisms capable of transforming atmospheric nitrogen into fixed nitrogen (inorganic compounds usable by plants). More than 90 percent of all nitrogen fixation is effected by these organisms, which thus play an important role in the nitrogen cycle.

The differences in height between two homozygous strains of a plant are AABBCC strain is 12 cm taller than aabbcc strain.

As a result, each dominant allele increases height by 2 cm over the baseline of 10 cm for the all-recessive strain. The genotype AaBbCc F1 will measure 10 + 6 = 16 cm. Given that each dominant allele is 2 cm, the six comes from the equation 2 * 3.

6 | 10+(2*6) = 22 | 1/64

5 | 10+(2*5) = 20 | 6/64

4 | 10+(2*4) = 18 | 15/64

3 | 10+(2*3) = 16 | 20/64

2 | 10+(2*2) = 14 | 15/64

1 | 10+(2*1) = 12 | 6/64

0 | 10+(2*0) = 10 | 1/64
