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.​

Answers

Answer 1

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.

Explain at least 3 adaptations that algae would need to be able to survive on land.

Answers

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

Myoglobin levels are higher in Tibetans and other ethnic groups that live at high altitudes. Explain the benefit of higher myoglobin levels for individuals living at high altitudes.

Answers

Answer:

They are able to take up and store more oxygen in their muscles

Explanation:

According to Oxford dictionary, myoglobin is ''a red protein containing haem, which carries and stores oxygen in muscle cells. It is structurally similar to a subunit of haemoglobin.''

The fact that Tibetans have a high level of myoglobin implies that they are able to take up and store more oxygen in their muscles since myoglobin is involved in storage of oxygen in muscle cells. Hence elevated levels of myoglobins enables the muscle cells to work more effectively.

If two individuals were heterozygous for freckles, which are a dominant autosomal trait, what percentage of their offspring would you expect to have freckles

Answers

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%

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?

Answers

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.

The correct answer is - intrasexual selection.

Explanation:

Intrasexual selection is the act of competing with other members of one's own sex for various reasons such as high status, mating, area, and many more as well as the evolutionary process responsible for this competition. The great examples of these are antlers of deers and big size showy feathers of the peacocks to attract their males.

Thus, the correct answer is - intrasexual selection.

Where does the egg receive its energy from?


options:


a. The ovum contains a large quantity of cytoplasm, which contains nutrients for the first days of development after fertilization. The cytoplasm of the ovum contains over 140 000 mitochondria to produce ATP required for growth.



b. The uterus contains over 140 000 mitochondria to produce ATP and supplies this to the egg for growth.



c. Similar to sperm it receives its energy from fructose through its path to the uterus.



d. The ovum contains a large quantity of fimbria, which contains nutrients for the first days of development after fertilization.

Answers

Answer:

Until attachment to the uterus, the developing organism is on its own. That means it needs to supply its own energy, so the cytoplasm of the human egg cell contains many energy-generating factories called mitochondria. Those mitochondria come only from the mother.
