Explain why bacteria and archaea are prokaryotic cells and all other organisms are eukaryotic cells
Answer:

Which is the most highly sensitive time within the developing embryo for the risk of malformation related to environmental teratogens
The most highly sensitive time within the developing embryo for the risk of malformation related to environmental teratogens is cleft palate at 8 weeks gestation. It is an opening in the roof of the mouth.
A teratogen is any substance and/or physical agent that may cause an irreversible abnormality in the structure of the developing embryo or fetus (e.g., classical pesticides such as DDT).
Cleft palate is a malformation mainly caused by mutagenic agents (teratogens) during pregnancy, which affects approximately one (1) of 650 births.
A cleft palate is a malformation that occurs when the two plates of the skull that form the roof of the mouth cannot be completely joined.

A student is given four components of evolution, shown in the four boxes here. Which statements can be formed using the terminology shown here to accurately describe the evolution within a species? Select ALL that apply.
Answer:
C and E
Explanation:
The key feature here is that individuals cannot evolve. Individuals are either adapted in their movement. This is how evolution by means of natural selection occurs.
The statements which can be formed using the given terminology are: Individuals have different genetics, leading to the evolution of populations. Individuals with adaptations are based on genetics, allowing for populations to undergo evolution. Thus, the correct options are C and E.
What is Evolution?Evolution can be referred to as the change in heritable characteristics of biological populations over the period of successive generations. These characteristics are the expressions of genes, which are passed on from the parents to their offspring during the process of reproduction.
The statements which can be formed using the given terminology include: 1. Individuals have different genetics, leading to the evolution of populations. 2. Individuals with adaptations are based on genetics, allowing for populations to undergo evolution

Explain how hydrogen fuel cells work, and why they provide a healthy, clean way to produce heat and electricity. (Site 1).
Answer:
As there are no moving parts, fuel cells operate silently and with extremely high reliability. Due to their chemistry, fuel cells are very clean. Fuel cells that use pure hydrogen fuel are completely carbon-free, with their only byproducts being electricity, heat, and water.

are genes for green seeds similar to yellow genes? Explain your answer.
Answer:
Explanation:
There is no “yellow” gene in the peas found on farms. ... Mendel's experiments showed that green is the recessive seed color in pea plants.
Since yellow is dominant to green, all of the offspring were yellow.
Rabbits and sheep both graze on shrubs, grasses, and other plants. The sharp rise in the population of rabbits in a region may result in a shortage of plants for sheep to graze upon.
This relationship between sheep and rabbits is an example of _______.
A.
parasitism
B.
predation
C.
commensalism
D.
competition
The answer is D) competition.
We can see from the problem that the two animals are competing with one another. As the number of rabbits increases, the competition between the food source increases. This is why predators are important for the environment, as the level out the playing field for both animals.

two pieces of information along with their sources
Answer: No
According to BBC, Human activities such as harvesting plants and hunting animals can unbalance the flows and cycles within those [SMALL SCALE ECOSYSTEMS ]ecosystems. Tree-felling may lead to soil erosion and a loss of habitat. Lack of shade and moisture in the soil can result in desertification.
According to National Geographic, Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.

how does an autoimmune disease affect the muscular system?
Answer:
Explanation:
Myositis (my-o-SY-tis) is a rare type of autoimmune disease that inflames and weakens muscle fibers. Autoimmune diseases occur when the body's own immune system attacks itself. In the case of myositis, the immune system attacks healthy muscle tissue, which results in inflammation, swelling, pain, and eventual weakness.
identify the explanations researchers suggested to explain differences in health and mortality by gender.
The differences in health and mortality by gender is a phenomenon for which researchers have many possible explanations.
There have been studies that have indicated that there is enough variation in the average health of males and females to conclude that there are factors at play that are affecting health.
Amongst the many possibilities, scientists have mentioned:
Gender-reliant genetic vulnerability Hormonal factorsDifferences in physiologyas the main possible reasons.
Hormones play a big part in the health of each individual and are vastly different between genders, along with the endless differences in physiology at a molecular level. These factors together may explain why some members of a gender are more vulnerable to genetic illness.

why is it important for gametes to be haploid jiskha
Answer:
its important for gametes to be haploid so when fusion of the Male and female gametes take place after fertilization the correct amount of chromosome numbers specific to the species can be restored
It is important for gametes to be haploid as just to maintain the chromosomal number. It is present for the sake of incorporation of both of the sets of chromosome in the progeny.
What is the number of chromosomes in humans ?It is having 23 pairs of chromosomes that is having total of 46 chromosomes.
Because meiosis just creates cells which are destined to be the gametes and in this reduction in the chromosome number is just critical that is without the process, the union of the two gametes that are during the fertilization that will result in the offspring with just twice of normal number of the chromosomes.
Haploid cells in the humans are just produced out by meiosis. This is type of the cell division in which the single diploid parent cell just divides to just produce four with the non-identical type of the haploid daughter cells. In meiosis is just used to get the type of the produced type of gametes and is are a necessary kind of precursor to the sexual reproduction.

What diagnostic test is useful for detecting hyperactivity of the thyroid gland during an evaluation of a thyroid disorder
Answer:
Blood tests that measure thyroxine and thyroid-stimulating hormone (TSH) can confirm the diagnosis. High levels of thyroxine and low or nonexistent amounts of TSH indicate an overactive thyroid. The amount of TSH is important because it's the hormone that signals your thyroid gland to produce more thyroxine
