A solution that is equal in solute concentration to that of the cytoplasm of a cell and causes a cell to neither lose nor gain water by osmosis is a(n)
Answer:
isotonic solution
Explanation:
The cell membrane is semi-permeable, so it allows to pass through certain solutes. By a process called osmosis, the water molecules move from a compartment of lower concentration of solutes to a compartment with higher concentration.
Therefore, if the concentration of solutes in the outside is higher than the concentration in the cytoplasm (hypertonic solution), the water molecules will move from the interior to the exterior. Conversely, if the cytoplasm is more concentrated than the outside (hypotonic solution), the water molecules will move from the exterior to the interior. If the cytoplasm has the same solute concentration as the outside, the solution of the outside is called isotonic, and no water net flux will be produced.

Explain at least 3 adaptations that algae would need to be able to survive on land.
Answer:
1. Algae have a variety of adaptations that help them survive including body structures, defense mechanisms, as well as reproductive strategies. Some algae have holdfasts that attach to the sea floor and anchor them down much like roots of a plant. Many algae, such as Sargassum, have gas-filled structures called floats.
2. Algae and plants are like humans as they need food, nutrients and a good environ- ment to grow and survive. Algae make their own energy or food from the sun but they also need water, correct temperature and nutrients to grow. Algae live in water or damp environments
3. In addition to making organic molecules, algae produce oxygen as a by-product of photosynthesis. Algae produce an estimated 30 to 50 percent of the net global oxygen available to humans and other terrestrial animals for respiration
Explanation:

Answer:
1. Adaptation for life on land. The stomata can open and close depending on weather in algae.
2. vascular is tissue is not necessary since the entire.
3. seedless plants are classified onto three main catagories
Scenario 1:
Genetic engineering can be used to create more productive strains of farm animals used for milk and meat production. By adding genes to an animal’s DNA, the animal can be made to be more resistant to common infections. This can reduce the need to administer large doses of antibiotics to the animals.
Do you think that this type of genetic engineering should be pursued? Explain your answer. (5 points)
What are some possible impacts (positive and negative) of this type of genetic engineering on individuals, society, and the environment? (5 points)
Answer:
Yes.
Explanation:
Yes, this type of genetic engineering should be pursued in order to avoid decrease in death through infections or diseases as well as increase the production of milk and meat of that animals. With this genetic engineering, organisms have high resistance to diseases which decrease the cost of antibiotics. The positive effect of this genetic engineering is the increase in the resistance that leads to good health as well as productivity of organism.

Until DNA evidence provided evidence to the contrary, flagellated spores were used to group the blastocladiomycetes with the ____.
Answer:
Chytridiomycetes
Explanation:
Blastocladiomycetes were initially grouped under the phylum Chytridiomycetes within the fungi kingdom because the former also have flagellated spores just like the latter
The similarity in spores initially made scientists classify both groups as zoosporic fungi. However, DNA and structural analysis of the spores of the two groups showed that Blastocladiomycetes has no monophyletic relationship with Chytridiomycetes.

In a population of mole-rats, some have a little larger teeth and longer claws. If those particular mole-rats survive because they can dig quicker and the others are preyed on and do not survive to reproduce, what will eventually happen in subsequent generations?
Answer:
One increase in population and the other decrease.
Explanation:
The population of the rats having little larger teeth and longer claws increases as compared to those rats having small teeth and shorter claws because the rats can escape from their predators and survive in that environmental conditions. The population of rats having small teeth and shorter claws extinct in the end due to no reproduction and preyed by the predators and dominated by the population of the rats having little larger teeth and longer claws due to their features.

Which of the following proteins could be used to carry proteins across the
cell membrane?
Answer:
The answer is B :)
Explanation:
Proteins pass through the membrane through passive transport. So the protein used to carry protein through integrated channel membrane. so the correct option is C.
What are proteins?A protein is a naturally occurring complex substance which consists of amino acid residues joined by peptide bonds.
Passive transport is defined as movement of a solute from a region of high electrochemical potential to a region of lower electrochemical potential on the opposite side in cell membrane. The figure representing the protein transportation through protein carrier channel.

If two individuals were heterozygous for freckles, which are a dominant autosomal trait, what percentage of their offspring would you expect to have freckles
Answer:
75%
Explanation:
Firstly, an autosomal dominant trait is a trait the becomes expressed in the presence of only one affected allele, which is the dominant allele. Freckles is said to be an autosomal dominant trait meaning that the presence of the dominant allele (F) makes a person have the condition.
According to this question, If two individuals that are heterozygous for freckles cross i.e. Ff × Ff, the following proportion of offsprings will be produced: FF, Ff, Ff and ff (see punnet square).
From the genotypic observation of the produced offsprings:
FF, Ff - possess freckles
ff - do not possess freckles
Since, 3 (FF, Ff and Ff) of 4 offsprings possess freckles, the percentage of offsprings expected to have the condition will be:
3/4 × 100 = 75%
