What property of steroid hormones allows them to cross the phospholipid bilayer?.
Answers
The phospholipid bilayer is Steroid hormones that are lipid soluble and readily cross the phospholipid bilayer.
Since steroid hormones are lipid-derived hormones they can cross the plasma membrane by simple diffusion. This means it can pass through every cell in the body. Unlike other types of hormones, steroid hormones do not need to bind to plasma membrane receptors.
Steroid hormones produce changes inside the cell by first crossing the cell membrane of the target cell. Steroid hormones are able to do this because they are fat-soluble, unlike non-steroid hormones. Cell membranes are made up of phospholipid bilayers that prevent fat-insoluble molecules from diffusing into the cell. Steroids can freely diffuse through the lipid bilayer.

Cell respiratory is the system with the aid of which biological fuels are oxidized in the presence of an inorganic electron acceptor such as oxygen to supply big quantities of energy, to power the majority production of ATP.
Cell respiration is a chain of chemical reactions that spoil down glucose to provide ATP, which may be used as power to strengthen many reactions at some stage in the frame. There are 3 principal steps of cell respiratory: glycolysis, the citric acid cycle, and oxidative phosphorylation.
Cellular respiratory is the procedure by which food, within the form of sugar (glucose), is transformed into energy inside cells. Mobile respiration is the method with the aid of which cells in plant life and animals damage down sugar and flip it into electricity, which is then used to carry out work on the cellular degree. The motive of cell respiration is simple: it presents cells with the energy they need to feature.

Suppose you wanted to determine whether you had adequately sampled the species richness of a given community. Which result would lead most strongly to the conclusion that the current sampling had adequately assessed the species diversity? a A species accumulation curve that reaches a plateau b A gradually increasing Gini coefficient that then decreases
c A low Shannon index value d A high Shannon index value
Answers
The species accumulation curve that reaches a plateau would lead most strongly to the conclusion that the current sampling had adequately assessed the species diversity.
The species accumulation curve shows the relationship between the number of individuals sampled and the number of species observed. If the curve reaches a plateau, it indicates that the sampling effort has captured most of the species diversity in the community. However, if the curve is still increasing rapidly, it suggests that more sampling is needed to adequately assess the species richness. Therefore, a species accumulation curve that reaches a plateau would indicate that the current sampling had adequately assessed the species diversity.

method of dispersal and characteristics of dandelions?
Answers
Answer: Dandelions are flowering plants that belong to the family Asteraceae. There are several methods of dispersal that dandelions use to spread their seeds and reproduce.
Explanation:
One method of dispersal for dandelions is wind dispersal. Dandelions have lightweight seeds that are equipped with a fluffy, white pappus, which is a group of long, fine hairs. This pappus allows the seeds to be carried by the wind, which helps to disperse them over long distances.
Another method of dispersal for dandelions is through their fruit, which is a type of dry, one-seeded fruit called an achene. Dandelion achenes are equipped with a sticky, hooked beak that helps them adhere to the fur of animals, clothing, or other objects. When an animal brushes against a dandelion plant, the achenes can be transferred to the animal's fur and carried away, helping to disperse the seeds.
Some other characteristics of dandelions include:
Dandelions have bright yellow flowers that are typically about 1 to 2 inches in diameter.
The leaves of dandelions are long and deeply lobed, and they are typically found in a rosette pattern around the base of the plant.
Dandelions are herbaceous plants, which means that they have non-woody stems and leaves that die back to the ground in the winter.
Dandelions are found in a variety of habitats, including grasslands, fields, meadows, and gardens. They are also commonly found in urban areas, as they are able to grow in a range of soil types and are resistant to many environmental stresses.
Dandelions are known for their long taproots, which can reach depths of up to several feet. This helps the plant to access water and nutrients from deep in the soil, making it difficult to remove from the ground once established.
Dandelions are edible and are often used in salads, teas, and other dishes. They are also used in traditional medicine for their medicinal properties.
Dandelions are considered to be a weed by many people, as they can quickly spread and compete with other plants for resources. However, they are also important food sources for a variety of animals, including bees, butterflies, and other insects.

A population of plants absorbs necessary nutrients from the soil. The
nutrients are not recycled into the soil after the plants die. Which statement
best describes how a graph of the plant population would look over time?
OA. The graph would show exponential growth until the population
levels off and stabilizes.
OB. The graph would show logistic growth and then exponential
growth after plant death occurs.
OC. The graph would show exponential decline until the population
levels off.
D. The graph would show logistic growth until the population sharply
decreases.
Answers
The given scenario describes a situation where the nutrients absorbed by the plant population are not recycled back into the soil after the plants die. Therefore, option D, "The graph would show logistic growth until the population sharply decreases," would be the most accurate description.
The plant population would likely show logistical growth until it reached the carrying capacity of the environment, at which point it would level off and remain relatively stable. The carrying capacity represents the maximum number of individuals that can be supported by the available resources in the environment, such as nutrients in the soil. However, if the nutrients are not being recycled into the soil, the carrying capacity would decrease over time, which would eventually result in a decline in the plant population.

Later in life, in another round of meiosis, a single nondisjunction event occurs in meiosis II involving the only the X sister chromatid pair. All other chromosome segregation (in meiosis I and meiosis II) occur as normal. What are ALL of the possible gamete genotypes for genes F and XJ that could result from this round of meiosis? (HINT: consider independent assortment, it might help to draw out and track the chromosomes and nondisjunction.).
Answers
Sister chromatids (meiosis II) or homologous chromosomes (meiosis I) fail to split during meiosis, resulting in nondisjunction. Sister chromatids in one daughter cell, however, migrate into the same gamete during anaphase II of Meiosis II instead of being able to split.
Because the sister chromatids were unable to separate during anaphase II, nondisjunction in meiosis II resulted. Meiosis I went off without a hitch, thus two of the four daughter cells will contain the typical complement of 23 chromosomes. With n+1 and n-1, respectively, the other 2 daughter cells will be aneuploid. Meiosis I and meiosis II can both result in nondisjunction, which can lead to abnormally few gametes with chromosomes.

To help your investigation, here is some more data about the farm.
How should I include my data?? Will give points and I picked natural selection
Answers
To write an inclusive hypothesis from investigation, it should be structured with Mechanism of Evolution, Hypothesis and Data.
How to hypothesize?Mechanism of Evolution
The mechanism of evolution that I think caused the increase in FQ resistance is natural selection. Natural selection is the process by which organisms that are better adapted to their environment are more likely to survive and reproduce. In this case, the bacteria that are resistant to FQ are more likely to survive and reproduce because they are not killed by the drug. This means that the population of bacteria will become more resistant to FQ over time.
Hypothesis
My hypothesis is that the increase in FQ resistance in the bacteria on the farm is due to natural selection. I believe that this is because the bacteria that are resistant to FQ are more likely to survive and reproduce, which means that the population of bacteria will become more resistant to FQ over time.
Data
The new data supports my hypothesis because it shows that the number of bacteria that are resistant to FQ has increased. The data also shows that the bacteria that are resistant to FQ are more likely to be found in the environment where the FQ is being used. This suggests that the bacteria are evolving to become resistant to the FQ.
How to Include the Data
You can include the data in your hypothesis by stating that the increase in FQ resistance is due to the fact that the bacteria that are resistant to FQ are more likely to survive and reproduce. You can also include the data by showing a graph of the number of bacteria that are resistant to FQ over time.
This is an example of how to include the data in the hypothesis:
I hypothesize that the increase in FQ resistance in the bacteria on the farm is due to natural selection. This is because the bacteria that are resistant to FQ are more likely to survive and reproduce, which means that the population of bacteria will become more resistant to FQ over time.
