On a recent field trip, you discover a new species of plant. Since you are interested in plant reproduction, you rear the plant

over several generations to study its life cycle. All of the reproductive cells you collect are haploid; however, those formed by meiosis are able to develop directly into a new plant, while those formed by mitosis are unable to do so. You conclude that the haploid cells formed by mitosis are __________.

Answer:

Gametes

Explanation:

The given plant has a haploid plant body. Haploid gamete mother cells undergo mitosis and form haploid gametes. The gametes should be fused together to give rise to a diploid zygote. The diploid zygote then undergoes meiosis and gives rise to the haploid plant body.  

The haploid plant body bears haploid gamete mother cells and the process continues. The given plant exhibits zygotic meiosis and forms gametes by mitosis.

Answer:

Connective tissues that attach muscle to bone.

Explanation:

The tissues that connect, bind, support or separate other tissues or other organs are called Connective Tissue. There are three major types of connective tissue -

  1. Loose connective tissue
  2. Dense connective tissue
  3. Specialized connective tissue

Tendon and Ligaments come under dense connective tissue category. Tendon is a fibrous connective tissue and connects muscles to bone. It has capability to withstand tension.

Ligaments connect bones to bones.

The second generation phenotypes resulting from the cross of purebred monohybrid pollination will display a ratio of _____. 2:2
Art [367]
The answer is 3:1.

If we imagine that plant has two alleles for the trait, we can dominant allele represent with P represents and recessive allele with p. To get purebred monohybrid in the first generation, parents must be a dominant homozygote (PP) and a recessive hetero<span>zygote (pp):

Parental generation: PP   x   pp
The first generation: Pp  Pp  Pp  Pp

Pp represents a heterozygote.
If we cross these heterozygotes:

The first generation: Pp   x   Pp
The second generation: PP  Pp  Pp  pp

If dominant allele determines the phenotype, there will be 3 plants (one PP and two Pp) with one phenotype and only 1 plant </span><span>(pp)</span> with another phenotype and vice versa.

In neuroscience, depolarization is an "all or nothing" response; what does that
Tom [10]

Answer:

The correct answer is - The neuron's intracellular charge must get more positive to meet a certain  thresh hold in order to depolarize. If the neuron does not hit that threshold, then the  neuron will not fire

Explanation:

In neuroscience, the depolarization of neurons shows the all or none law which is also called as all or nothing response. It states that all action potentials have the same size and the potential or strength of a nerve cell does not depend on the stimulus strength as all are the same size.

If a stimulus reaches a particular threshold cell or fiber will fire so either it will fire or not cross the threshold this is all or nothing response or law and depolarization is an example of it.
