Which element of an original work can be changed in an adaptation? Theme. Story. Setting. Main idea.

The theory of plate tectonics was at first rejected by geologists and the more comprehensive theory later replaced it.

The continents were "drifting" over the surface of the planet, occasionally crashing into one another and into seas.

As we know,

Wegener's theory was largely rejected since he offered no explanation for how the continents may move.

The name of the theory was theory of plate tectonics.

Thus, the theory of plate tectonics that was at first rejected by geologists and the more comprehensive theory that later replaced it.

Answer:

Its actually A

Explanation:

The enzyme that covalently connects segments of DNA is 1) ligase.

Ligase plays a vital role in DNA replication, repair, and recombination by catalyzing the formation of phosphodiester bonds between adjacent DNA segments. During DNA replication, DNA polymerase synthesizes new DNA strands in a discontinuous manner on the lagging strand, resulting in short DNA fragments called Okazaki fragments. Ligase then joins these Okazaki fragments by sealing the gaps between them, creating a continuous DNA strand.

In DNA repair, ligase is responsible for repairing nicks and single-stranded DNA gaps by sealing the broken ends. It is also involved in DNA recombination processes, where DNA segments from different sources are joined together.

In summary, ligase is the enzyme that covalently connects segments of DNA by catalyzing the formation of phosphodiester bonds, ensuring the integrity and continuity of the DNA molecule

Prepare a note on the need of conserving biodiversity.

Bioremediation is that process which use the biological organisms to protect and repair the environment.

Bioremediation refers to the use of biological agents or processes in order to protect and repair the environment from negative human impacts. This phenomenon depends on stimulating the growth of specific type of microbes that utilize contaminants such as oil, solvents and pesticides as a sources of food and energy.

These microbes has the ability to use these harmful substances as a food and convert these contaminants into water as well as harmless gases like carbon dioxide so we can conclude that bioremediation is that process which use the biological organisms to protect and repair the environment.

The testes and ovaries are similar because both produce sex cells that fuse during the process of fertilization to produce a zygote cell (Option D is correct).

The testes and ovaries are reproductive organs in males and females, respectively, which generate germinal meiotic cells (i.e., sperm and ovules)to be used during the fertilization process.

Many yeast metabolism-related genes resemble bacterial genes more so than archaeal genes, which is a discovery that shows eukaryotes and bacteria may have had a more recent common ancestor.

The majority of the genes in eukaryotic genomes come from bacteria. 56% of eukaryotic genes are on average from bacteria, 53% come from eukaryotes without plastids, and 61% come from photosynthetic eukaryotic lineages, where the cyanobacterial ancestor of plastids contributed more genes to the eukaryotic lineage. In order to adapt to the nutrient-rich environment of the cells they infect, intracellular parasites go through a process of reductive evolution in which they give up bacterial genes involved in metabolic functions. The human parasite Encephalitozoon intestinalis, which has 86% genes of archaeal and 14% of bacterial origin, exhibits the most dramatic adaptive gene loss.

Explanation:

Answer:

A. Small size.

B. A single cell or unicellular.

C.it has one chromosome which is not true and it is called plastid.

Explanation:

This is because prokaryote are unicellular organisms that lack nucleus and membrane bound organelles. The are smaller in size compare to eukaryotic, which have large surface to volume ratio. They lack mitochondria, Golgi apparatus, endoplasmic recticulum, e t.c. They have only one chromosomes which is not even a true one and it is called plastid. Examples of prokaryote include bacteria.

The phenotypic difference between a person with CC genotype and one with CG is related to the ability to produce the protein erythropoietin (EPO), which is important in the production of red blood cells.

The CC genotype individuals are homozygous for the wild-type allele, which results in normal EPO production, whereas CG genotype individuals carry one copy of a variant allele that affects EPO production and function.

Individuals with the CG genotype may have a reduced ability to produce EPO, which could affect their ability to produce more red blood cells at high altitudes.

This may result in a decreased oxygen-carrying capacity and a higher risk of developing altitude sickness or other related conditions. However, the exact impact of the CG variant on altitude adaptation is complex and may depend on other genetic and environmental factors as well.

The best action to help the bat population would be to provide undisturbed areas to attract insects, as bats feed on insects.

Bats primarily survive on a diet of insects, such as mosquitoes, moths, flies, and beetles. Some species of bats also feed on fruit, nectar, or small vertebrates like frogs and lizards.

Bats play an important role in controlling insect populations and helping to pollinate plants, making them important to many ecosystems.

Using insecticides to eliminate insects, using herbicides to eliminate weeds, and removing trees can all negatively impact the bat's food source and habitat.

Answer: Horses and donkeys have different numbers of chromosomes. Therefore, the offspring (mule) is unable to make sperm or eggs. This is because a horse and a donkey have different numbers of chromosomes. Horses have 64 and donkeys have 62. The baby gets half from the horse (32) and half from the donkey (31). When they combine they have a total of 63. During meiosis, when the chromosomes split, there is 31 pairs with 1 left over that cannot pair with another chromosome. This prevents all of the chromosomes from pairing so the sperm or eggs cannot be made.

True.

Explanation:

Because genetic mutations effect not only humans but animals too. Its how things evolve, like humans. So yes.

The correct answer is C. probably evolved from one single ancestral species from the mainland. Darwin realized that Finches differed form their relatives in mainland. The finches he saw were all particular on their own, so he concluded that their isolation from mainland and their insular habitat make them to evolve different traits, eventually each finch become a different species.

Answer:

mRNA is “messenger” RNA. ... The process of making mRNA from DNA is called transcription, and it occurs in the nucleus. The mRNA directs the synthesis of proteins, which occurs in the cytoplasm. mRNA formed in the nucleus is transported out of the nucleus and into the cytoplasm where it attaches to the ribosomes.

Answer:

Ribosomes create the thermoreceptors of the body. Another example of a homeostatic condition maintained by proteins is blood-glucose levels. When our blood-sugar levels get too high, specialized cells in the body release a protein hormone called insulin.

Answer: Ribosomes play a key role in homeostasis. Without ribosomes, a cell would not make proteins. A cell with no ribosome would simply not function. With no protein reproduction to maintain the cell wall there would be no barrier to keep invasive bodies from damaging the inner workings of the cell, there would be no way to produce the needed proteins for rebuilding and maintaining the cell.
