The blood CARRIES oxygen, nutrients, hormones and other important materials throughout the body as it circulates.

Pseudogenes are non-functional copies of genes that have lost their ability to code for functional proteins. They are explained by evolution through the process of gene duplication, where a copy of a gene may acquire mutations that render it non-functional, but the original gene still retains its function.

Pseudogenes are remnants of genes that were functional in the evolutionary past, but due to mutations, they have become non-functional. Pseudogenes arise through a process called gene duplication, where a copy of a gene is made, and the new copy may evolve and lose its original function. Pseudogenes provide evidence for evolution by showing how mutations can accumulate in non-functional genes over time, leading to the evolution of new functional genes or the loss of functions in genes.

Based on various physical properties, objects can be classified and grouped together.

A specific criterion is size, which allows objects to be classified as small, medium or large. Another factor in grouping is shape, such as whether an object is round, rectangular, or triangular. Whether it is based on primary colors or on a particular color palette, color provides a visual basis for classification.

Differentiating between smooth, rough and bumpy surfaces depends on the texture. Objects can be classified based on whether they are made of wood, metal or plastic, so the composition of the material is also important. The criterion of weight is used to classify objects as light, medium or heavy. The function of an object can be used to group items with related applications or purposes.

Main Answer: The important citric acid cycle intermediate that is also formed during gluconeogenesis from pyruvate is Oxaloacetate.

Supporting Answer: During gluconeogenesis, pyruvate is converted to oxaloacetate by the enzyme pyruvate carboxylase. Oxaloacetate is an important intermediate in the citric acid cycle, where it reacts with acetyl-CoA to form citrate. In the citric acid cycle, citrate is then metabolized through a series of reactions to produce energy in the form of ATP. In addition, oxaloacetate plays a crucial role in the regulation of the citric acid cycle by controlling the rate of entry of acetyl-CoA into the cycle. It is also involved in several other metabolic pathways such as the aspartate synthesis pathway and the urea cycle. The formation of oxaloacetate during gluconeogenesis is important because it allows the carbon skeletons of certain amino acids to be converted to glucose for energy production.

Lactobacillus is the genus commonly found in the resident biota of the mouth, large intestine, and female genital tract from puberty to menopause, playing a crucial role in maintaining the body's health.

Lactobacillus is a genus of Gram-positive, facultatively anaerobic bacteria that are commonly found in various parts of the human body, including the mouth, large intestine, and female genital tract. They are considered a part of the normal resident biota in these areas and play an important role in maintaining the body's health.

In the mouth, Lactobacillus species are involved in maintaining the natural balance of bacteria, which helps prevent the growth of harmful bacteria that can cause dental caries or gum disease. In the large intestine, they help in the digestion of food and the production of vitamins such as vitamin K, as well as preventing the overgrowth of harmful bacteria.

Within the female genital tract, Lactobacillus species are important in maintaining a healthy vaginal microbiome, which can help prevent the overgrowth of harmful bacteria that can cause infections such as bacterial vaginosis. Lactobacillus produces lactic acid, which lowers the vaginal pH and creates an acidic environment that inhibits the growth of pathogens.

During puberty to menopause, the presence of Lactobacillus in the vaginal microbiome is particularly important, as it helps maintain the proper pH and suppresses the growth of harmful microorganisms. Hormonal changes during this time can affect the composition of the vaginal microbiome, which can lead to an overgrowth of pathogenic bacteria and the development of infections.

A parent species can still exist when a new "daughter" species evolves because the process of speciation, or the formation of new species, does not necessarily require the extinction of the parent species.

A daughter species is a new species that has evolved from a parent species. The term is commonly used in the context of speciation, which is the process by which new species arise. Speciation occurs when a population of a species becomes isolated from other populations of the same species and evolves independently.

Speciation can occur in a variety of ways, but it generally involves a population of a species becoming geographically or reproductively isolated from other populations of the same species. Over time, the isolated population may accumulate genetic differences and adaptations that distinguish it from the parent population, eventually leading to the formation of a new species.

However, the parent species may still persist and continue to evolve separately from the daughter species. This can happen because the isolated population that gives rise to the daughter species may only represent a small subset of the parent species' total genetic diversity.

Alternatively, the isolated population may eventually reunite with the parent population and exchange genetic material, which can lead to continued evolution in both populations.

Answer:

Analogy

Explanation:

Cave catfish and cave earthworms can be said to have analogous traits, which have over the years developed separately and have different ancestral origins. This new analogous trait is as a result of the need for both organisms in their different environments, which seem similar in condition, to adapt well.

Through convergent evolution analogous structures and traits are usually formed or observed in organisms that do not share the same ancestral origin.

The diversity that refers to all the different genes contained in all members of a population is genetic diversity.

The correct answer is A.

Gene diversity is the diversity of individuals within one species of living thing. Gene diversity results in variations between individuals of the same kind. Examples of diversity at this gene level are white roses, red roses, and yellow roses which have differences, namely differences in terms of flower color.

Statement is true about enzyme-catalyzed reactions is d. The reaction proceeds faster than the same reaction in the absence of the enzyme.

Enzyme-catalyzed reactions are chemical reactions that are accelerated by enzymes, which are biological catalysts. These enzymes lower the activation energy required for the reaction to occur, allowing it to proceed at a faster rate than it would without the enzyme.

This increased rate does not alter the Delta G (change in free energy) of the reaction (option a) and does not mean the reactions are all exergonic (option b).

he reaction does not proceed quickly because of increased activation energy, but rather because the enzyme lowers the activation energy (option c).

Answer:

Anaphase

Explanation:

Anaphase is when the spindle fiber seperate the sister chromatids to seperate sides

"Gliders" are small insects that are capable of traveling on water due to a combination of physical phenomena involving hydrogen bonding, surface tension, adhesion, and cohesion.

Surface tension is a liquid property caused by the cohesive forces between liquid molecules. Because of hydrogen bonding, water molecules are strongly attracted to one another, resulting in a high surface tension of water. This high surface tension forms a thin, elastic film on the water's surface, allowing small objects like insects to float on it.

Adhesion refers to the attraction of molecules of different substances. Gliders, for example, have specialised hydrophobic (water-repellent) structures on their legs that prevent them from breaking the surface tension of water and sinking. The hydrophobic structures on the insects' legs repel water and adhere to surface tension, allowing the insects to stay on the surface.

The attractive forces between molecules of the same substance are referred to as cohesion. Water molecules' cohesive forces form a surface film that is strong enough to support the weight of small objects like gliders. Insects that travel on water, such as gliders, can distribute their weight over a large area by increasing the contact area with the water's surface with their hydrophobic legs. This reduces the pressure on the water's surface tension, allowing the insects to float on top.

In summary, gliders travel on water due to the combination of hydrogen bonding, surface tension, adhesion, and cohesion. The hydrophobic structures on the insects' legs repel water and adhere to the surface tension of water, allowing the insects to remain on the surface. The cohesive forces between water molecules create a surface film that is strong enough to support the weight of the insects, allowing them to float on the surface.
