____________ livestock are produced with extra copies of growth hormone genes to allow them to grow faster and produce meat that is low in fat.

Answer:

Smaller single-celled organisms have a high surface area to volume ratio, which allows them to rely on oxygen and material diffusing into the cell (and wastes diffusing out) in order to survive. The higher the surface area to volume ratio they have, the more effective this process can be.

I had the same question in my test

When constructing phylogenies to accurately reflect evolutionary history, the presence of polyphyletic taxa and paraphyletic taxa is problematic. Monophyletic taxa, on the other hand, are desirable for constructing accurate phylogenies.

A phylogeny is a graphical representation of the evolutionary relationships among organisms. It aims to depict the true evolutionary history by grouping organisms into monophyletic taxa, which include a common ancestor and all its descendants. Monophyletic taxa ensure that all members within the group share a common evolutionary origin.

Polyphyletic taxa, option 2, are problematic because they consist of unrelated organisms that do not share a recent common ancestor. The inclusion of polyphyletic taxa in a phylogeny leads to incorrect evolutionary relationships and undermines the accuracy of the reconstruction.

Paraphyletic taxa, option 3, are also problematic as they include some, but not all, descendants of a common ancestor. By excluding certain descendants, paraphyletic taxa distort the true evolutionary relationships and hinder our understanding of the evolutionary history.

Therefore, option 1 and option 2 are both problematic when constructing phylogenies that accurately reflect evolutionary history, while option 3 (paraphyletic taxa) is also problematic. Option 4 (monophyletic taxa) is the desired classification as it ensures that the groupings accurately represent the evolutionary relationships among organisms.

Explanation:

Small leaves - these ensure that less water is lost from the plant by transpiration because the leaf has a smaller surface area.

Tap roots - these are long roots (7-10 metres long) that reach deep under the ground to access water supplies. The tap roots are much longer and bigger than the plant which is visible at the surface.

Spines - some plants have spines instead of leaves, eg cactuses. Spines lose less water than leaves so are very efficient in a hot climate. Spines also prevent animals from eating the plant.

Waxy skin - some leaves have a thick, waxy skin on their surface. This reduces water loss by transpiration.

Water storage - some plants, known as succulents, store water in their stems, leaves, roots or even fruits. Plants which store water in their leaves and stems also have a thick waxy skin so that they lose less water by transpiration.

Answer:Octopuses ability to squirt ink.

Physiological adaptations are those adaptations which occurs at the metabolic level in the organisms. These adaptations occurs in the cells, tissues and organs of the body of the organism in response to external environmental stimulus. Physiological adaptations are beneficial for the survival of the organisms against predators. These adaptations generates a defense mechanism in the body of the organism, in order to increase it's chances of survival.  

Octopuses ability to squirt ink is an example of physiological adaptations as the ink is released in the water by these organisms in order to escape themselves from predators.  

Explanation:

The sensation of tickling or discomfort that you may feel when trying to hold your breath for an extended period of time is due to the buildup of carbon dioxide (CO2) in your bloodstream.

When you inhale, oxygen enters your lungs and is transported to your body's cells through the bloodstream. As the cells use oxygen to produce energy, they also produce CO2 as a waste product. The CO2 then travels back to the lungs, where it is exhaled out of the body.

When you hold your breath, the body's cells continue to use oxygen and produce CO2. However, since you are not exhaling, the CO2 builds up in your bloodstream, causing the blood to become more acidic. This change in pH triggers the body's respiratory center, which sends a signal to the lungs to breathe in air and release the CO2.

The sensation of tickling or discomfort that you feel is your body's way of telling you to breathe in air and release the CO2. If you continue to hold your breath, the discomfort may increase and eventually become painful, and you may also start to feel dizzy or lightheaded due to the lack of oxygen.

The pair of terms "Bacteriostatic-kills vegetative bacterial cells" is mismatched. Bacteriostatic refers to a substance that inhibits the growth and reproduction of bacteria, but does not necessarily kill them.

In contrast, a bactericidal substance kills bacteria. Vegetative bacterial cells are actively growing and dividing cells, which are vulnerable to bactericidal agents, but may survive exposure to bacteriostatic agents. Therefore, it is important to distinguish between bacteriostatic and bactericidal agents, as their modes of action and effects on bacterial populations differ significantly.

Bacteriostatic agents are commonly used in combination with other therapies or preventive measures to limit bacterial growth and spread, while bactericidal agents are used when rapid and complete eradication of bacteria is necessary. Understanding the difference between these terms is essential for effective treatment and prevention of bacterial infections.

There are different kinds of cells because of differential expression of the genome. Meaning only the expression of some genes of the entire genome.

All the cells in an organism have the same genome. Cells of different stages and different lineages express different kinds of genes. This is due to factors like imprinting, effect of cellular signaling etc. A stem cell would not be expressing the entirety of the genome, it expresses genes that lead to synthesis of proteins like telomerase, as the cell differentiates, the telomerase synthesis is halted. If it were not so, the cell would be immortal. This is observed in some cancers.

Cells do not become specialized during mitosis. This process occurs during the G0 stage. Cells only divide then. And take up fates based on the environment and the cellular signals.

The cells having the same origin have chromosomes that are already present in the parent cell. In case of gametogenesis the cells may have different numbers of chromosomes and an anomaly, occurrence of mutations can change the number of chromosomes in a cell.

The cells of an organism share the same genetic content, which means they would have the same chromosomes, and do not undergo differentiation during mitosis. It is only after the division that the differentiation occurs. The cells of different specializations actually express different genes. This gives rise to different cell types in the body. An example is that secretion of insulin is only carried out in beta cells of pancreas.

Therefore, There are different cells due to different cells expressing different genes.
