Answer:
the answer is chloroplasts
Explanation:
The answer is D) 1/2.
Let's imagine that two genes of the genotype can be analysed separately.
Black fur is determined by dominant allele B. In this case, parents Bb and BB will give offspring with only brown fur:
Parents: Bb x BB
Offspring: BB BB Bb Bb
Both homozygous (BB) and heterozygous (Bb) offspring will have black fur.
On the other hand, long tails are determined by recessive allele t. Parents Tt and tt will have 50% offspring with short tail and 50% offspring with long tail:
Parents: Tt x tt
Offspring: Tt Tt tt tt
Heterozygous offspring (Tt) will have short tail, and homozygous offspring (tt) will have a long tail.
So, the offspring will definitely have black fur and will not affect the fraction of the offspring with black fur and long tails from the cross of <span>BbTt × BBtt. But, </span>there will be 2 out of 4 offspring with short tails which is 50% or 1/2.
Indeterminate cleavage results in identical cells capable of forming an embryo while determinate cells do not result in cells which are capable to develop embryo.
Indeterminate is superior to determinate cleavage.
Explanation:
Cleavage is the division of cells in the early embryonic stage. The two stages of cleavage described here are:
In indeterminate cleavage or regulative cleavage occurs when an embryo divides, each cell is capable of developing into complete embryo. eg: Deuterosomes
In determinate cleavage the resulting embryonic cells of blastomere cannot develop into embryos. It is also called as mosaic cleavage. The essential part of the cell might be missing which does not let the cell survive. eg: Protosomes
Indeterminate cleavage is of great importance as the cell grows and can produce new organism. The complete identical twin is formed. Its application can be seen in tomato plants.
3. All animals do not display intermediate cleavage because growth from intermediate cleavage is continuous and does not stop after adulthood which is not possible in animals.
Answer:
constructing dams and building desalination plants help reduce the effects of droughts
Explanation:
Answer:
1. It produces a very deep sound.
2. It combines the vocal and vestibular folds at the same time.
3. It causes the vibration of the vestibular folds. A vibration cycle culminates at the second vibration.
4. There are basically two types, namely the Dag and Xovu styles.
5. It resembles a Tibetan Buddhist chant.
Explanation:
Khoomii, also known as Tuvan throat singing is a way of singing mostly characterized by the production of deep sounds and vibrations. A basic pitch which is supplemented by another pitch combine to produce the sound. It is sung by the locals in Siberia and Tuva.
Kargyraa is one of the four forms of this song and it typically involves the production of deep sounds and some vibrations of the vestibular folds at times. There are two basic types which are the Dag and Xovu. It also has a similarity to the chant produced by the Tibetan Buddhists.
