Punnett's Squares
These show the 2 alleles of each parent plant crossed with each
other and the resulting 4 possible offspring with T= tall, = short.
TT = dominant tall, 17 = recessive short, Tt = mixed hybrid
TT = dominant tall (genotype tall, phenotype tall)
Tt = mixed hybrid (genotype hybrid, phenotype tall)
tt = recessive short (genotype short, phenotype short)
Using the Punnett's Squares below, name the offspring of all possible parent combinations

Answer:

9:7

Explanation:

We get the dominant phenotype in plants that have at least one dominant allele of EACH of the two genes; otherwise we get the recessive phenotype. So, the observed ratio in the F2 generation is 9:7.

So, this is your answer.

Answer:

The correct answer is - per gram, the marathon runner's muscles would contain more myoglobin than the sprinter's muscles.

Explanation:

Marathon runners have smaller leg muscles and thinner quads and calves as marathon runners require slow-twitch muscles while in sprinters the fast-twitch muscle requires. Slow-twitch muscles of marathon runners have more amount of myoglobin, per gram than fast-twitch muscles.

Myoglobin acts as local oxygen storage that provides oxygen to the muscles in case of less oxygen supply than required temporarily and a marathon race is an intense exercise or activity that requires more oxygen.

The BEST example of a point source of water pollution is factory effluent (Option c).

Water pollution refers to the contamination of water with pollutants. These substances (i.e., pollutants) convert water unusable to carry out different activities (e.g., drinking, cleaning, etc).

Water pollutants include, among others, herbicides, food processing waste, volatile compounds, heavy metals, organic pollutant microorganisms (e.g. bacteria, parasites), etc.

Factory effluents are well known to be harmful water pollutants for aquatic ecosystems.

In conclusion, the BEST example of a point source of water pollution is factory effluent (Option c).

Answer:

Number of wolves, and harshness of winter.

Explanation: I took the test

The combination of factors that is capable of limiting the population of elk in an ecosystem would be the number of wolves and the harshness of winter.

The limiting factors of a population are those factors that hinder the population of an organism from increasing unlimitedly. In other words, limiting factors hinder populations from reaching their biotic potentials.

Limiting factors can be density-dependent if they have correlations with the density of species or density-independent if they have no correlation with an organism's density.

Wolves generally prey on elks, so they limit the growth of elk's population in an ecosystem. A harsh winter will also limit the overall growth of the population of elk in an ecosystem.

Scavengers cannot be a limiting factor to elk's population because they only feed on carcasses.

More on population limiting factors can be found here: https://brainly.com/question/24077456

Explanation:

Biotic factors such as the presence of autotrophs or self-nourishing organisms such as plants, and the diversity of consumers also affect an entire ecosystem. Abiotic factors affect the ability of organisms to survive and reproduce. Abiotic limiting factors restrict the growth of populations.

Answer:

A. The digestive system fuels the cells and the excretory system rids the body of the cells’ waste.

Explanation:

got it right on edg quiz (see pic)

hope this helps :)

All nutrients that enter the circulation are processed by the digestive and excretory systems simultaneously, with the exception of oxygen, which is taken in by the respiratory system. The correct answer is a) The digestive system fuels the cells and the excretory system rids the body of the cells’ waste.

Nutritive substances are absorbed by the digestive system, and any that are not are expelled. By continuously purging the blood, the excretory system works in tandem to remove metabolic waste products from cells throughout the body.

The digestive system takes in the nutrients and water from the diet. All across the body, the circulatory system delivers nutrition, water, and oxygen to cells. The respiratory system, the excretory system, and the skin all remove waste from the cells.

The excretory system filters the bloodstream for nutrients and gathers unneeded components in your urine for disposal, whereas the digestive system absorbs nutrients, collects them, and then eliminates the undigested solids (feces).

Therefore, the correct answer is a).

Answer:

feeding

Explanation:

when an organism eats another, it gets energy from it. That energy is passed along the food chain

The process by which energy is transferred from organisms at one stage in a food chain to organisms at the next is by feeding, which is present in the second option, as through the eating process and the predator-prey relationship, energies pass.

The food chain in nature is made up of many trophic levels, where one trophic level animal preys on other animals or plants and obtains food from them, so when the animal is eaten by other animals, the energy content passes from one to another, and the energy content from plants continues to decrease to the topmost trophic levels.

Hence, the process by which energy is transferred from organisms at one stage in a food chain to organisms at the next is by feeding, which is present in the second option, as through the eating process and the predator-prey relationship, energies pass.

Explanation:

Answer:

The answer is Protozoa

Explanation:

Answer:

2.447 × 10⁴ years

Explanation:

Step 1: Given data

Step 2: Calculate the rate constant

Radioactive decay follows first-order kinetics. We can calculate the rate constant (k) using the following equation.

k = ln2 / (t1/2) = ln2 / 3,500 y = 1.980 × 10⁻⁴ y⁻¹

Step 3: Calculate the time elapsed (t)

For first-order kinetics, we will use the following expression.

ln ([A]/[A]₀) = -k × t

t = ln ([A]/[A]₀)/ (-k)

t = ln (1/127) / (1.980 × 10⁻⁴ y⁻¹) = 2.447 × 10⁴ y
