The tissue you are referring to is called the "protective tissue" or "protective layer", which is a type of plant tissue that is responsible for protecting the plant from various external factors such as injury, water loss, and infection.

There are different types of protective tissues found in different parts of the plant. For example, in roots, the protective tissue is the root cap, which covers the tip of the root and protects it as it grows through the soil. In stems and leaves, the protective tissue is the epidermis, which is a thin outer layer that provides a barrier against water loss and infection. The epidermis also often contains specialized cells such as trichomes or hairs that provide additional protection.

In flowers, fruits, and seeds, the protective tissue is often the outer layer of the structure, such as the skin of a fruit or the seed coat of a seed.

Lemurs, lorises, and bush babies are considered descendants of the earliest primates because they share several key characteristics with the earliest known primates that lived over 55 million years ago. These characteristics include:

1. Grasping hands and feet - These primates have opposable thumbs and big toes that enable them to grip branches and move through trees more easily.

2. Forward-facing eyes - This feature provides depth perception and better vision for hunting and avoiding predators.

3. Large brains - Compared to other mammals of similar size, primates have larger brain-to-body size ratios, which may have contributed to the development of complex social behaviors.

4. Nails instead of claws - Most primates have flat nails on their fingers and toes instead of curved claws to aid in gripping and manipulating objects.

5. Arboreal lifestyle - The earliest primates were tree-dwellers, and lemurs, lorises, and bush babies are all adapted to life in the trees, with long limbs and flexible joints that allow them to move quickly and efficiently through the branches.

For these reasons, scientists believe that lemurs, lorises, and bush babies share a common ancestor with the earliest primates and are often referred to as "prosimians," which means "before monkeys."

Answer: parasitism can help shape biodiversity by exerting selective pressure on host populations and by contributing to the diversity of parasitic organisms themselves.

Explanation: Parasitism is a form of symbiotic relationship where one organism, the parasite, benefits while the other, the host, is harmed. Parasites can have a significant impact on the biodiversity of an ecosystem by selecting and shaping the characteristics of their host species.

Parasites have evolved to infect specific hosts, which means that their survival and reproduction are tied to the existence of their host. As a result, parasites can exert selective pressure on the host population, favoring certain traits and characteristics that make the hosts more resistant or susceptible to infection.

This selective pressure can lead to evolutionary changes in the host population, which can lead to increased genetic diversity. For example, if a parasite infects a population of fish and selects for fish that have more effective immune systems, then those fish will be more likely to survive and reproduce, passing on their advantageous traits to their offspring. This can ultimately lead to the development of new species.

Furthermore, parasites themselves can be incredibly diverse. Studies have shown that parasites can account for a significant percentage of the total biodiversity in an ecosystem. By infecting different hosts and adapting to different environments, parasites can influence the evolution of their hosts and contribute to overall biodiversity.

Answer:

Parasitism, in common with competition, facilitation, and predation, could regulate BD-EF relationships. Parasitism affects host phenotypes, including changes to host morphology, behavior, and physiology, which might increase intra- and interspecific functional diversity.

Interference competition and varying population sizes help balance ecosystems. Option C is correct.

This is the best explanation of why Makayla is wrong. While it may seem like an abundance of one species means the ecosystem is unbalanced, this is not necessarily the case. Interference competition, where individuals of the same or different species compete for resources, can help to balance the ecosystem by regulating population sizes. Additionally, the size of populations can naturally vary over time due to factors such as environmental conditions, predation, and disease. Therefore, an ecosystem with a large population of one species does not necessarily indicate an imbalance. Option C is correct.

Answer:

The outer/inner membranes of a chloroplast do not absorb photons for the photosynthesis process.

Explanation:

The main role of the outer membrane of a chloroplast is to act as a protective barrier, regulating the entry and exit of molecules into and out of the chloroplast. The inner membrane, on the other hand, plays a crucial role in regulating the transport of molecules between the cytosol and the stroma of the chloroplast.

Photosynthesis, which involves the conversion of light energy into chemical energy, takes place in the thylakoid membranes located inside the chloroplasts. These thylakoid membranes contain chlorophyll pigments that absorb photons of light, initiating the process of photosynthesis.

The distance that an oxygen molecule would travel by diffusion through blood vessels depends on various factors such as the concentration gradient, temperature, and the surface area of the blood vessels. However, on average, it is estimated that the diffusion rate of oxygen in blood is approximately 0.2-0.3 millimeters per second. Therefore, it would take around 3,333 seconds or 55.5 minutes for an oxygen molecule to travel 1 meter by diffusion alone. This highlights the vital role that the circulatory system plays in efficiently transporting oxygen throughout the body.

A. Plant A, deprived of water for two weeks, will experience drought stress, leading to wilting, stunted growth, and potentially death.
B.  Plant B, receiving necessary conditions, will continue to grow healthily, benefiting from proper hydration, nutrient uptake, and overall vigor.

A. Plant A, when subjected to a two-week period without watering, will undergo significant stress due to drought conditions.

This stress will cause the plant to exhibit signs of wilting as its cells lose turgor pressure.

Its growth will likely be stunted, as the plant conserves water by reducing metabolic processes like photosynthesis.

Prolonged water deprivation may lead to the plant's inability to recover, ultimately resulting in death.

Additionally, the plant's reproductive potential may be compromised due to reduced energy investment in flower and seed production.

B. Plant B, provided with all necessary conditions like water and fertilizer, will continue to grow in a healthy manner. Adequate hydration will ensure that the plant can maintain optimal cell turgor pressure, leading to proper growth and development.

Access to essential nutrients through fertilizer will support vital metabolic processes, including photosynthesis, respiration, and nutrient uptake.

As a result, Plant B will display healthy foliage, vigorous growth, and a greater likelihood of successful reproduction through the production of flowers and seeds.

The probability for that one of their children will also be a carrier for the disorder is 50% probability to be a carrier. Option B is correct.

Correct Punnett square for this scenario is:

| | A | a |

---|---|---|---|

| A | AA| Aa|

| a | Aa| aa|

In this Punnett square, both parents are heterozygous carriers, which means they both have one copy of the normal allele (A) and one copy of the disease-causing allele (a). The probability of each child inheriting a copy of the disease-causing allele is 50%, and the probability of each child inheriting a copy of the normal allele is also 50%.

Therefore, the probability of one of their children being a carrier for the disorder is 50%. This means that the child will have one copy of the normal allele and one copy of the disease-causing allele, like the parents. However, the child will not have the disorder because they need two copies of the disease-causing allele (one from each parent) to express the disorder.

It is also important to note that this is a simplified model and that many genetic disorders are more complex than a simple dominant or recessive pattern of inheritance. Additionally, genetic testing and counseling may be necessary for couples who are carriers of genetic disorders to understand the risks of passing on the disorder to their children.
