3a. Scientists think some organisms have eyespots on their bodies to help them lure in prey. Choices True False

Answers

Answer 1
Answer:

Answer:

False

Explanation:

The eye spot instead creates a disguise and used to misdirect predators. The eyespots are a defense mechanism for the organism. Scientists have tested this by painting eye spots on a gake prey and a fish was used a s the predator. The predator was discovered to have attacked the fake eyespots more often as it thought it was the prey's head.

Eyespots on a prey can also make the predator to think that it is facing a larger animal. An example is the butterfly which have large false eyes on its wings.

About 3 million Brazilian free-tailed bats live near Fredericksburg, Texas, in an abandoned railroad tunnel. Eighty percent of the free-tail's diet includes agricultural pests such as the cutworm, corn borer, and webworm moths. Each can eat its weight in insects nightly, and the whole colony may devour over 25 tons of moths per night. The bats return to the tunnel between midnight and daybreak, having traveled an average 25 to 30 miles to forage. As the population of bats increases, it is expected that the crop production in nearby areas will —

A pea plant is heterozygous for both seed shape and seed color. S is the allele for the dominant, spherical shape characteristic; s is the allele for the recessive, dented shape characteristic. Y is the allele for the dominant, yellow color characteristic; y is the allele for the recessive, green color characteristic. Think about the gametes this parent plant will produce. List the alleles in each gamete.

Answers

During gametes production, alleles randomly separate producing different combinations in daughter cells. The gametes in this example are YS, Ys, yS, ys.

How are gametes formed?

Gametes are formed during meiosis. Meiosis is a cell division process that produces gametes from germ cells. Through Meiosis, a diploid cell (2n) produces four haploid daughter cells (n).

According to the segregation principle, alleles separate independently during gametes formation.

In anaphase I, homologous chromosomes separate, and each of them migrate to the opposite poles of the cell carrying one of the alleles. This random event leads to different chromosomal combinations in the daughter cells.

Now, let us analyze the problem,

Plant ⇒ heter0zyg0us for both seed shape and seed color ⇒ SsYy

  • S is the dominant allele and codes for spherical shape
  • s is teh recessive allele and codes for dented shape
  • Y is the dominant allele and codes for yellow
  • y is the recessive allele and codes for green

Gametes) YS, Ys, yS, ys.

So, you would make a punnet square. You would put the capital S and lowercase s on the top of it and then the capital Y and lowercase y on the side. Then you should have SY, sY, Sy, and sy as your outcomes.

Explain why an ecological pyramid is smaller at the top than at the bottom

Answers

Because energy is wasted as heat, there is less energy available as food for organisms at each level above so ecological pyramid is smaller at the top than the bottom.

What is Ecological pyramid?

  • .An ecological pyramid is a graphical representation of the relationship between diverse living organisms at various trophic levels.
  • These pyramids have the shape of true pyramids, with the widest base and the lowest trophic level, i.e., producers, covering it.
  • The following trophic level, i.e. main consumers and so on, is occupied by the next trophic level.
  • The uppermost level of an energy pyramid has the fewest animals since it has the least amount of energy.
  • Most ecosystems only have four trophic levels since there isn't enough energy to support another at a certain point.
  • The energy produced by the plants is distributed to the a pex predator in the amount of 0.01 percent.
  • As a result, it makes logical that the pyramid's tiers grow smaller and smaller as you progress up the pyramid.

The ecological pyramid is a diagram that shows the very much like amounts of energy or matter contained within each level. That's why it is shaped smaller at the top than at the bottom because the bigger it is the more the organisms are there are. So the bottom has more living organisms and the top has less. Hope this made sense and helped

If a geneticist is studying what each allele combination looks like-its visible expression in an organism, height, hair color, eye color-the geneticist is studying an organism's........ a) Genotype b) Phenotype c) Karyotype d) Genomics

Answers

Answer:

If a geneticist is studying the visible expression of allele combinations in an organism, such as its height, hair color, and eye color, they are studying the organism's phenotype. Therefore, the correct answer is b) Phenotype.

Water and minerals are transported from the roots to the rest of the plant through the phloem. True or false?

Answers

The statement for the transport of water and minerals from roots to plant by phloem is false.

The transport of food, water, and minerals from the roots to the leaves is mediated by the vascular tissues xylem and phloem in the plants.

Which vascular tissue carries water and minerals?

The water and minerals are absorbed by the plant's roots from the soil, and are transported from the roots to the stem and leaves by the process of osmosis.

The transport of food in the plants is carried by phloem tissues, and the transport of water and minerals is carried by the xylem tissues.

Thus, the given statement is false.
