Answer:

Animal migration is the relatively long-distance movement of individual animals, usually on a seasonal basis. It is the most common form of migration in ecology. It is found in all major animal groups, including birds, mammals, fish, reptiles, Many of these migrations are north-south, with species feeding and breeding in.

Explain the meaning of the term "tetrad" as applied to the asci produced by certain fungi.

zalisa [80]

Answer:

Explanation:

In the members of the class ascomycetes such as yeast, two haploid yeast cells of two different stains or mating types fuse to form a diploid zygote. Zygote quickly undergoes meiosis or reductional division to form four haploid spores called a tetrad. The tetrad is contained in a sac-like structure called an ascus or fruiting body. Formation of ascus is the characteristic feature of ascomycetes. In the ascus tetrad are not arranged in any specific order. The tetrad are called random or unordered spores. The genetic analysis of the genotypes in the tetrad can tell us about the events during meiosis.

A grow seeded purple flowered heterozygous plant (YyPp) is crossed with a green seeded, white flower plant (yypp). What is the p

vredina [299]

Question:

A <u>yellow</u> seeded, purple-flowered heterozygous plant (YyPp) is crossed with a green seeded, white-flowered plant (yypp).

(Y = yellow seed allele; y = green seed allele; P = purple flower allele; p = white flower allele)

What is the probability that an offspring of this cross produces plants with green seeds and white flowers? Assume the traits assort independently.

Answer:

The probability that an offspring of this cross produces plants with green seeds and white flower is 25% = 0.25

Explanation:

<u>Available data</u>:

Y = yellow seed allele; Dominant
y = green seed allele; Recessive
P = purple flower allele; Dominant

p = white flower allele; Recessive
the traits assort independently

Cross: A yellow seeded, purple-flowered heterozygous plant with a green seeded, white-flowered plant

Parentals) YyPp x yypp

Gametes) YP, Yp, yP, yp yp, yp, yp, yp

Punnett square)

YP Yp yP yp

yp YyPp Yypp yyPp yypp

F1) 4/16 = 1/4 = 25% YyPp, Yellow seeds and Purple flowers

4/16 = 1/4 = 25% Yypp, Yellow seeds and white flowers

4/16 = 14 = 25% yyPp, green seeds and purple flowers

4/16 = 1/4 = 25% yypp, green seeds and white flowers.

The probability that an offspring of this cross produces plants with green seeds and white flower is 25% = 0.25

BaLLatris [955]

Blood vessels that have thinner walls that are more likely to collapse when blood is withdrawn during a venipuncture are called veins.

Differently form arteries, veins are blood vessels with thin, less muscular walls. Veins have thinner walls because the blood pressure in them is much lower.

So, as a result of common intravenous injections (such as venipuncture), collapsed veins might occur. Veins are then temporarily blocked.
