Explanation:

If you are neither relaxing or contracting a specific muscle, the amount of ATP is A. staying the same or increasing.

Muscle cells require ATP as a source of energy for contraction and muscle movement. Even when you are setting your muscle to a relaxing mode, you are using some ATP to do so.

However, if a muscle is set in such a state that it is neither relaxing not contracting, hence there is no work being performed by the muscle. At this stage the ATP amount inside this muscle will remain the same and can increase if the neurons bring some extra ATP for the muscle cells to store here.

Although a part of your question is missing, you might be referring to this question:

If you are neither relaxing or contracting a specific muscle, what is happening to the amount of ATP that is available in that muscle cell?

A. It is staying the same or increasing.

B. It is decreasing rapidly.

During exocytosis, SNARE complexes enable vesicle fusion with target membranes is a True statement.

Exocytosis is a form of active transport that occurs in cells. It occurs when cells release molecules, such as proteins or neurotransmitters, by fusing vesicles with the cell membrane. The process of exocytosis begins with the fusion of a vesicle and the cell membrane. The vesicle and membrane fuse together, releasing the contents of the vesicle outside of the cell.

During this process, SNARE proteins play an important role in ensuring that the vesicle fuses with the correct target membrane. This process of fusion occurs due to the formation of SNARE complexes. The answer to the question is True. SNARE complexes are proteins that are essential for the fusion of vesicles with the target membrane during exocytosis. They ensure that the vesicle fuses with the correct target membrane.

Both directional selection and polyploidy speciation can play important roles in shaping the distribution and movement of species on the landscape. While directional selection influences the gradual adaptation of traits within a population, polyploidy speciation can lead to the emergence of new species with unique characteristics, facilitating their movement and expansion into different habitats.

Directional selection and polyploidy are two different mechanisms that can drive speciation, or the process by which new species arise from existing ones.

Directional selection refers to the process by which natural selection favors certain traits over others within a population, leading to the evolution of new traits and the differentiation of populations into new species. Directional selection can occur when a population is exposed to a changing environment, and certain traits become more or less advantageous in response to that change. For example, if a population of birds is exposed to a changing climate, birds with longer beaks may be better able to access new food sources, and their population may grow faster than birds with shorter beaks. Over time, this can lead to the evolution of a new species with a longer beak.

Polyploidy speciation refers to the process by which a population of organisms undergoes genetic changes that result in the production of offspring with multiple sets of chromosomes. Polyploidy can occur through a number of mechanisms, such as hybridization, polyploidization, or aneuploidy. When a polyploid organism is produced, it may have different genetic makeup than its parent species and may be better able to adapt to changing environmental conditions. Over time, this can lead to the evolution of a new species with different traits and characteristics.

Polyploidy speciation can occur relatively quickly, as the production of polyploid offspring can result in the fixation of new genetic traits in a population. Directional selection, on the other hand, can occur more slowly, as it relies on the gradual accumulation of advantageous traits over many generations. However, both mechanisms can contribute to the process of speciation and the evolution of new species on the landscape.

This results in these species being unculturable because their growth may depend on necessary growth factors provided by other organisms in their natural environment.

Certain bacterial species have specific requirements for growth that are not easily replicated in laboratory conditions. These bacteria may rely on the presence of other organisms in their natural environment to provide essential growth factors or nutrients. These growth factors could include specific compounds, co-factors, or signaling molecules that are produced by other organisms in their ecological niche. Without the presence of these necessary factors, the bacteria may fail to grow or reproduce in laboratory media, making them difficult to culture.

This specialization and dependence on other organisms create challenges in isolating and cultivating these bacteria in a laboratory setting. Researchers often need to replicate the complex interactions and conditions found in the natural environment of these unculturable bacteria to successfully culture them. This can involve using specialized growth media, co-culturing techniques, or even mimicking specific ecological niches to provide the necessary growth factors and conditions for their cultivation.

It's important to note that while options a, b, and d may be factors that affect the growth of certain bacterial species, the most accurate answer in this context is option c, as it specifically addresses the dependence of unculturable bacteria on necessary growth factors provided by other organisms in their natural environment.

Answer:

At 20 weeks gestation, the cellular structure of the __________ of the fetal lungs is complete.

Explanation:

The alveoli are tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place. These structures play a crucial role in respiration, allowing for efficient gas exchange between the lungs and the bloodstream. The development and maturation of alveoli are essential for the proper functioning of the respiratory system.

By 20 weeks gestation, the cellular structure of the alveoli has reached a stage of completeness. However, it is important to note that full lung development and the ability to function independently typically occur closer to the end of pregnancy, around 34 to 36 weeks gestation. At this stage, the surfactant, a substance that helps keep the alveoli open and prevents lung collapse, is also adequately produced.

It is a seeded vascular plant.

It does not depend on insect pollination.

Explanation:

The complete question is: A scientist has discovered a new plant species in the Amazon rainforest. She tells her fellow scientists that the plant she has found produces a cone. What might they say about how this plant is different from an angiosperm? Its seeds have one or two cotyledons. Its stems' vascular bundles are scattered. It does not depend on insect pollination. It is a seeded vascular plant.

The correct option would be that the plant is a seeded vascular plant and does not depend on insect pollination.

Gymnosperms are the only group of plants that produce cones. They are one of the plant groups that have vascular tissues in the form of xylem and phloem as well as been able to produce seed in the form fo cones. Hence, they are said to be seeded vascular plants.

Gymnosperms also carry out their pollination by relying solely on wind for the transfer of their pollen grain to the female organ. In other words, they do not depend on insect for pollination.

The advantage for plants having undigestible seeds is that it allows seeds to reside in the gut until conditions are appropriate for germination.

Fruits are a source of nutrition for animals that consume them, and they are also a means of seed distribution for plants that produce them. Many types of plants generate fruit that is consumed by animals; nevertheless, the seeds of such plants are usually indigestible. As a result, the seeds can be dispersed into new areas by animals that eat the fruit.

However, having undigestible seeds provides a distinct benefit to plants: it allows seeds to reside in the gut until conditions are appropriate for germination, which aids in seed growth and germination.
