Answer:
Lipase is an enzyme which breaks down fats/lipids into fatty acids and glycerol
Answer:
lipase is an enzyme protein
Explanation:
Select the statements that are true. Question 1 options: CO2 and O2 are water-soluble molecules that diffuse freely across cell membranes. The differences in permeability between artificial lipid bilayers and cell membranes arise from variations in phospholipid content. Transporters are similar to channels, except that they are larger, allowing folded proteins as well as smaller organic molecules to pass through them. Cells expend energy in the form of ATP hydrolysis so as to maintain ion concentrations that differ from those found outside the cell.
Answer:
CO2 and O2 are water-soluble molecules that diffuse freely across cell membranes.
Cells expend energy in the form of ATP hydrolysis so as to maintain ion concentrations that differ from those found outside the cell.
Explanation:
CO2 and O2 are highly soluble molecules in water due to their polarizability and their ability to react with water molecules and form new compounds. CO2 is 30 times more soluble in water than oxygen, which also has a high solubility. This ability allows these two molecules to diffuse freely across cell membranes.
Cells promote hydrolysis, that is, the breakdown of ATP molecules when they need to expend energy for any metabolic process, especially when they need to maintain a balance between ion concentrations inside and outside the cell. This is because ATP is a highly energetic molecule and its breakdown promotes energy for the cell to use in its activities.

do all organisms undergo cellular respiration
Answer:
No.
Explanation:
Cellular respiration takes place in the cells of all organisms. It occurs in autotrophs such as plants as well as heterotrophs such as animals. Cellular respiration begins in the cytoplasm of cells.
Though there is an exception of bacteria and yeast.
It occurs in most organisms but not all.
Answer:
No
Explanation:
Some bacteria and organisms like yeast go through fermentation which is actually a process we go through when we work our muscles, it produces that stinging feeling because our body uses fermentation and produces a mild acid because of that. Also, this is how alcohol is made.
Should people be allowed to use gene therapy to enhance basic human traits such as height intelligence or athletic ability?
Answer:
no, of course not
Explanation:
Would you use drugs to gain a competitive advantage in sports? No, its against the rules and also unethical. It's not healthy. You've seen Jurassic Park right? It would lead to ruin.

What are the different ways living organisms can evolve? How are they similar and different?
If all life is genetically related, as must be true if evolutionary theory is true, then species that are closer to humans on the evolutionary tree based on physical characteristics should also share a higher percentage of DNA compared with species that are less similar. Sure enough, we now know that humans share approximately 99.5% of genes with other humans, 98% of genes with chimpanzees, 93% with monkeys, 92% with mice, 90% with cats, 84% with dogs, 80% with cows, 60% with chickens, 44% with fruit flies, 26% with yeast, 18% with plants, and 7% with bacteria.

Write about why you think the earth moves and how. (I know is geology but they don't have that, sorry.)
Answer:
Earth spins because of the way it was formed
Explanation:
Our Solar System formed about 4.6 billion years ago when a huge cloud of gas and dust started to collapse under its own gravity. As the cloud collapsed, it started to spin. The Earth keeps on spinning because there are no forces acting to stop it.
what is the essence of setting up experiments in replicates?
Answer: Importance of replication in experiments
Explanation: Getting the same result when an experiment is repeated is called replication. ... Replication is important in science so scientists can “check their work.” The result of an investigation is not likely to be well accepted unless the investigation is repeated many times and the same result is always obtained.
what allows for differences between individuals due to differences in inherited DNA?

John is in his forties and his blood pressure reading shows consistently 160/100 mm of Hg. Name the disease. Mention any four reasons for such a condition?
Answer:
Stage 2 hypertension
Explanation:
Hypertension is a body circulatory system condition whereby the pressure of the blood vessels are raised persistently. The heart pumps blood to the different organs of the body through the blood vessels, each time it beats
The normal blood pressure in the vessel = 90/60 mmHg to 120/80 mmHg
The blood pressure of a prehypertension person or person at risk of having hypertension = 120-139/80-89 mmHg
The blood pressure at Stage 1 hypertension = 140/90-99 mmHg
The blood pressure at Stage 2 hypertension = 160/100 mmHg.

Which graph represents selection that may lead to reduced variation
in a population?
The frequency graph represents selection that may lead to reduced variation in a population.
Identify the statement that describes the imperfection of natural selection. Identify the statement that describes the imperfection of natural selection. Natural selection has not had sufficient time to create the optimal design in each case but will do so given enough time. Natural selection is generally limited to modifying structures that were present in previous generations and in previous species. In many cases, phenotype is not merely determined by genotype but by the environment as well. Though we may not consider the fit between the current skeletal arrangements and their functions excellent, we should not doubt that natural selection ultimately produces the best design.
Answer:
Variability was seen as imperfection, so natural selection could only eliminate the inferior and imperfect, not giving rise to new things, new species.

Describe how the lizard population is changing
Answer:
Each time lizards colonized an island, they evolved into many of the same forms. .Other lizards adapted to life among the thin branches lower down on the trees, evolving short legs that help them hug their narrow perches. Still other lizards adapted to living in grass and shrubs, evolving long tails and slender trunks.Lizards are low on the food chain. Providing protection from their natural predators ensures their continued existence. Plant bushy perennials, create a rock or brush pile or use man-made items like stacks of bricks or pipes.

Explain how specialized structures found in multiflora rose support its reproduction and spreading/dispersal throughout ecosystems in the United States. Use evidence and scientific reasoning to support your response.
Answer:
Presence of thorn stems, invasive nature and strong scent of of multi rose plant.
Explanation:
The presence of thorn stems, invasive nature and strong scent of of multi rose plant are the specialized structures found in multiflora rose support its reproduction and spreading and dispersal throughout ecosystems in the United States. The presence of thorn stems prevent animals to feed on the multi rose plant while on the other hand, strong scent of of multi rose flower attract pollinators that increase its pollination and increase occur in its population.
Your senior thesis project involves working out the taxonomy of Florida skinks. To accomplish this you examine skink specimens for morphological differences compare nucleotide and amino acid sequences and observe the skinks reproductive behavior and habitat types. Once you have completed the taxonomy and written the thesis you give it to your professor for comments. She tells you that you did a great job and should try to get your work published. However she suggests you indicate in the introduction what species concepts you used to make your classifications. What statement would you add
Answer:
I will add the following statement:
Taxonomic determinations were made based on the general lineage species concept.
Explanation:
Taxonomic determinations show inferred evolutionary relationships in the form of multiple branching lineages connected by nodes. So, the sequences can easily be identified at the end of branches. And these taxonomic determinations were made based on the general lineage species concept.
Hence, I will add the following statement:
Taxonomic determinations were made based on the general lineage species concept.
Mendel crossed yellow-seeded and green-seeded pea plants and then allowed the offspring to self-pollinate to produce an F2 generation. The results were as follows: 6,022 yellow and 2,001 green (8,023 total). Which of the following statements correctly describes the relationship of the allele for green soods to the allele for yellow seeds? A. The green allele is dominant to the yellow allele B. The two alleles exhibit incomplete dominance C. The green alicle is recessive to the yellow allele D. The two alleles are codominant
Answer:
C. The green allele is recessive to the yellow allele
Explanation:
Complete dominance occurs when one gene variant or allele referred to as the 'dominant allele' completely masks the expression of another allele referred to as the 'recessive allele' in heterozygous individuals, i.e., in individuals carrying one copy of the dominant allele and one copy of the recessive allele for a particular locus/gene (whereas homo-zygous individuals carry the same alleles for a given locus/gene). Mendel crossed pure lines of pea plants, i.e., homo-zygous lines for different traits such as seed color (yellow and green) and seed shape (round and wrinkled). In this case, the parental cross was YY x yy, where the 'Y' allele is dominant and encodes for yellow seed color, and the 'y' allele is recessive and encodes for green seed color. From this cross, Mendel obtained a hybrid F1 (i.e., all progeny was heterozygous with genotype Yy). An expected 3:1 ratio as observed in this case (6,022 yellow and 2,001 green seed >> 3:1 ratio) is characteristic of the progeny that results from mating between F1 heterozygous parents, where each parent has one dominant allele and one recessive allele, i.e., F1 parental cross: Yy x Yy >> F2: 1/4 YY (yellow color); 1/2 Yy (yellow color); 1/4 (green color) >> 3:1 ratio of yellow to green seeds.

how are the water cycle, carbon cycle, and nitrogen cycle different
In the water cycle, water changes between its various phases (solid, liquid and gas), but always stays water. In the case of the carbon and nitrogen cycles, various chemical forms of carbon (carbon dioxide, carbonates, sugars, etc.) and nitrogen (ammonia, nitrite and nitrate) are cycled through regularly.
When organisms die, decomposers in the ocean or soil break them down. Nitrogen in the soil or water is used again by living things. A small amount is returned to the atmosphere by certain bacteria that can break down nitrogen compounds into nitrogen gas. ... Show three ways in which water moves through the cycle.
Why is there a higher rate of skin cancer in Australia than in other
parts of the world?
Answer:
In Austrailia there is the highest rate of skin cancer because there is so much sunlight and most austalians have the wrong skin type for thier environment meaning people with pale skin get burnt more easily
Explanation:
Australia has a high rate of skin cancer because there's something different about the sunlight in Australia, and most people in Australia have skin that is easily damaged by light from the sun. Light carries energy that can make materials change. Therefore, Australia has a high rate of skin cancer because the ozone layer is damaged by the energy carried from the UV Light, being absorbed by the ozone and damaging allowing that light to transmit through and damage the genetic material of those individuals with lower levels of melanin.
