Answer:

Genetic material

Explanation:

Conjugation is one of the ways by which bacteria exchange their genetic material (horizontal gene transfer). Two bacterial cells must physically connect in order to perform the conjugation. The linking occurs through a pilus.

Pilus is an appendage on the surface of bacteria cell and it is also called fimbria. Pilus is  filamentous, tubular and composed of oligomeric proteins-pilin.

Donor cell contain pilus that will attach to the recipient bacterial cell and induce the transfer.

Answer:

D. A number of genetically resistant pesticide survivors reproduce. The next generation of insects contains more genes from the survivors than it does from susceptible individuals

Explanation:

Pesticide resistances in a population of insects usually occurs as a consequence of mutation. Individuals that carry the resistance mutation become favourable by natural selection.

Natural selection is evolutionary mechanism which favours traits of an organism that help him survive and reproduce. In the example, above,   resistant insects that survived after the use of pesticide had the favuoruable trait (resistance) by natural selection.

The statement "All organisms appeared on Earth at the same time and remained unchanged throughout history." is just a saying, it does not have any scientific evidence.

And in above option,

Answer:

The process of cell membrane synthesis is regulated.

Explanation:

The components of cell membrane (lipids, proteins, carbohydrates) are synthesized inside the cell organelles: endoplasmic reticulum and Golgi apparatus. After the synthesis, they are transported via vesicular transport also called vesicular trafficking. The transport is also very regulated process (molecules contain transport signal sequences). Components are secreted from the vesicles via exocytosis, when they arrive to their target location.

Answer:

archaeabacteria ( context clues can often give the answer :)

The prokaryotes most likely to be found living in extreme environments such as salt ponds or hot springs are archaea. Archaea are a distinct group of single-celled microorganisms that are genetically and biochemically different from bacteria. They are known to thrive in extreme environments, including high temperatures, high salinity, acidic or alkaline conditions, and high-pressure environments.

Archaea have been found in various extreme environments, such as hot springs, geothermal vents, deep-sea hydrothermal vents, salt ponds, and acidic or alkaline lakes. They have unique adaptations that allow them to survive and thrive in these harsh conditions. Some archaea are thermophiles, meaning they can withstand and even require high temperatures, making them well-suited for hot springs and geothermal environments.

Therefore, the prokaryotes most likely to be found living in extreme environments such as salt ponds or hot springs are archaea.

Cytotoxic T cells play a crucial role in the body's specific immune response by identifying and destroying cells infected with pathogens, with a few remaining as memory cells for faster response upon re-infection.

The specific immune response to pathogens involves the activation and function of cytotoxic T cells (CTLs). When these cells encounter infected body cells presenting specific pathogen antigens using Major Histocompatibility Complex (MHC) I molecules, they become activated. These activated cytotoxic T cells then use various mechanisms, such as releasing toxins, to destroy the infected cells, thereby containing the spread of the infection. These cells are particularly important when a pathogen has entered a cell, making it invisible to the humoral immune response which deals with pathogens in bodily fluids. The persistence of a few memory cytotoxic T cells after an infection ensures a quicker immune response if the same pathogen re-infects the body in the future.

Answer:

Explanation:

Yes, you got them all correct. GOOD JOB!!!!!!!

Answer:

C

Explanation:

Active transport is against gradient.. Or uphill movement.. So we have to spend energy.. Which are in the form of ATP(adenosinetriphosphate).

Active transport process require cellular energy to transport substance up their concentration gradients across the plasma membrane. Cellular energy usually in the form of ATP. Thus, c is correct option.

When movement of molecules is takes place then it is called active transport.

Active transport movement is always from lower concentration to a region of higher concentration gradients. So we can say that  substance are moving their own concentration gradients.

Active transport requires the signal or input of cellular energy in the form of ATP( adenosine triphosphate).

ATP is generally energy carrying molecule which are found in all living organisms. Active transport system are always sensitive to metabolic poisons because these metabolic poisons interrupt the ATP supply.

Therefore, active transport process require cellular energy to transport substance up their concentration gradients across the plasma membrane. Cellular energy usually in the form of ATP. Thus c is correct option.

Answer:

Offspring-heterozygous genotype SsEe

Explanation:

If we name the gene  for the body color with S and gene for the eye color with E and if the brown body is dominant over ebony body, while red eyes are dominant over sepia eyes, than the genotypes  of the parents would be: female-SSEE, male-ssee

P: SSEE  x  ssee

Female gametes SE, male gametes se

F1: SsEe all of the offspring would be heterozygous.

Final answer:

A cross between a white-eyed male and a heterozygous red-eyed female will produce offspring where 50% of the males have white eyes and 50% have red eyes and 50% of females are heterozygous for red eyes while the other 50% are homozygous for red eyes.

Explanation:

For a cross between a white-eyed male and a female that is heterozygous for red eye color, the possible genetic outcomes follow X-linked inheritance patterns. As females have two X chromosomes, a heterozygous female with one red-eye allele (XW) and one white-eye allele (Xw) can produce gametes with either allele. A male with white eyes (XwY) can only produce gametes with the white-eye allele on the X chromosome or the Y chromosome without this gene. Thus, 50% of their male offspring are predicted to have white eyes (XwY), inheriting the white-eye allele from either parent, and the other 50% will have red eyes (XWY), inheriting the red-eye allele from their mother and the Y chromosome from their father. Similarly, 50% of their female offspring will be heterozygous for red eye color (XWXw), while the other 50% will be homozygous for red eyes (XWXW) because they inherit the XW from their mother.

Runoff percipatation contributes to the dirty water because the rain water picks pollutants from the water and than it falls to the earth and than water continues and spreads into the large body of waters

The process of the water cycle that might contribute to the addition of pollutants to rivers, lakes, and oceans is runoff.

Runoff is exactly as it sounds. It is described as when water runs off the land. This water commonly drains towards:

and other bodies of water.

Though pollution is present in every part of the water cycle, it is most visible during runoff. During runoff, water travels downhill through the land, eroding the soil and carrying asking anything it finds asking the way, such as garbage. This garbage then end up in the larger bodies of water and contributes to their pollution.

Answer:

baleen whales are descendants of toothed whales.

Embryonic teeth in baleen whales are evidence of evolutionary history, indicating that these whales descended from toothed ancestors but have adapted to filter-feeding with baleen. This is part of broader patterns of adaptation in marine life, which include various forms of feeding strategies and physical changes due to evolutionary pressures.

The teeth of embryonic baleen whales are evidence that whales evolved from toothed ancestors. These embryonic teeth are vestigial structures, which are remnants of evolutionary history; they are present in the embryo but do not develop into functional teeth for the adult whale. Instead, baleen whales develop baleen, which is a keratin-based filtration system that allows them to efficiently filter feed on planktonic animals from seawater. This transition from teeth to baleen is reflective of evolutionary adaptations to different feeding mechanisms and environments. The baleen is used in place of teeth to capture small prey in a bulk feeding strategy, distinguishing them from toothed odontocetes such as dolphins and porpoises.

Similar evolutionary adaptations are seen in other marine animals, such as certain species of sharks and rays that evolved into suspension feeders. Whale evolution is also demonstrated in physical changes, such as the vestigial pelvic bones, which indicate their terrestrial mammalian ancestry and the secondary loss of hind legs as they adapted to an aquatic lifestyle.
