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%

Complete the sentence below by selecting the correct words from the drop-down menus. Factors that affect natural selection include , , and .
Answer:
The correct answer is -
variation, over population and adaption.
Explanation:
Natural selection is the process to which the various species and populations are able to adapt and change according the environmental changes. It is affected by three main factors that are variation, over population and adaption.
Variation: varion is one of the factor that pushes the population to change towards the beneficial variation in the population for their survivability and reproducing theirselves.
Overpopulation: over population increases the competition amon population and there fore there resources become limited so few have to change or their ways of utilizing resources.
Adaption: Adapting the change takes place due to any situation in environmental that put stress on the population allow them to adapt according the change or they will extinct.
Answer:
Variation, overpopulation, and adaption
Explanation:
I can confirm this is the right answer, because I just did the assignment.
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

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.

Determine which of the following statements is true about energy in ecosystems A. Consumers pass on 20% of the energy they get from a lower trophic level. OB. Primary consumers lose 60% of the energy they absorb from producers as urine and feces. C. 10% of the energy Primary consumers absorb is lost as heat. Ons Primary producers lose 20% of the energy they absorb as urine and feces.
Answer: C. 10% of the energy Primary consumers absorb is lost as heat.
Explanation:
According to the ten percent law of energy flow only 10 percent energy is transferred from one trophic level to the next trophic level and rest of the energy is used to develop the biomass and lost as heat. As the loss of heat is an essential exothermic reaction after the digestion and assimilation of food the energy is lost as heat from the body of the primary consumers is 10%. Primary consumers are animals that are dependent on plants for their food requirements for example deer, goat and others.
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.

Step by step explanation:
How can a scientist determine if two species are obligate mutualists? The scientist should observe the species in the environment to determine the types of interactions that the two species have. Then, the scientist should transplant each species alone to a new area and simultaneously transplant both species together to see if the single-species transplants die. The scientist should observe the species in the environment, determine the types of interactions that the two species have, and then add an invading species to see if it outperforms one of the other species. The scientist should observe the species in the environment, determine the types of interactions that the two species have, and then transplant both species to a new location to observe if they do better or worse than the individuals in their old location. The scientist should observe the species in the environment, determine the types of interactions that the two species have, and then remove one of the species to see if the other species does not survive.
Answer:
The scientist should observe the species in the environment to determine the types of interactions that the two species have. Then, the scientist should transplant each species alone to a new area and simultaneously transplant both species together to see if the single-species transplants die
Explanation:
When two species are obligate mutualists, both species benefit one another in such a way that one cannot survive without the other. Hence, in order to find out if two species are indeed obligate mutualists, they should be transplanted together away from other species on one side, and also transplanted individually on another side.
If they are obligate mutualists, the individual transplant would find it difficult to survive and should die in no time while the transplant done together should survive. All other factors being kept constant.
