Answer:
1. No, the process independent assortment randomly segregate the maternal and paternal chromosomes to different gametes.
2. No, the process of crossing over generates recombinant chromatids.
Explanation:
1. During anaphase-I of meiosis-I, the random segregation of maternal and paternal chromosomes to the opposite poles of the cell occurs. This process randomly distributes the homologous chromosomes of a pair to the gametes. Therefore, the progeny obtains some new combinations of maternal and paternal chromosomes that were not present in their parents. Further, the process of random fusion of these gametes adds more new combinations of chromosomes.
2. The process of crossing over generates the recombinant chromatids during prophase-I. This produces some new allele combinations on the chromosomes which were not present in the parental chromosomes.
Answer:
Independent assortment
Explanation:
The law of independent assortment says that genes for different traits or characteristics assort independently from each other during gamete formation. So each contrasting character's pair assort independently and do not show any association with the pair of other characters.
So after gamete formation collectively the gametes have all the possible combinations of alleles because all the genes are assorted independently in gametes.
This independent assortment of traits leads to some new combination of characteristics in the offspring. Therefore the correct answer is independent assortment.
Yes. Like many other fish, they reproduce by laying eggs.
Answer:
1. Greenhouse gases trap heat in the atmosphere warming the Earth’s temperature above freezing. This is known as the Greenhouse effect.
2.. The three greenhouse gases that are of most concern are Carbon Dioxide (CO2), Nitrous Oxide
(N2O), and Methane (CH4).
3.Without some greenhouse gases and the Greenhouse Effect, Earth’s temperature would be close to -18°C.
Explanation:
Answer:
A client who can complete range of motion with some resistance should be rated as grade 4 or 4/5 muscle strength.
Explanation:
The scale used to measure muscle strength is useful in determining conditions that affect the normal function of moving body segments, such as certain neurological conditions or muscle diseases.
The scale assigns a number, from 0 to 5, to evaluate the lesser or greater degree of muscle strength that exists:
- <em>No movement = 0.
</em>
- <em>Muscle contraction, no movement = 1 (1
</em>
- <em>Movement in one plane = 2 (2/5)
</em>
- <em>Movement against gravity = 3 (3/5).
</em>
- <em>Movement against a small resistance = 4 (4/5).
</em>
- <em>Normal movement = 5 (5/5).</em>
<u>The client can perform movements against a resistance, so it can be rated as 4/5 muscle strength</u>.
