B DNA sequence helps to identify characteristic of ancestors
Answer and explanation;
Slow spreading rate
Top middle- rift valley
Top Right- poorly- developed magma chamber
Rapid Speading rate
Top left- Swell
Top Right- Well- Developed magma chamber
Bottom middle- Diverging plates
Explanation;
-Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.
-This is what happens at the mid-oceanic ridge where a divergent boundary is causing two plates to move away from one another resulting in spreading of the sea floor. As the plates move apart, new material wells up and cools onto the edge of the plates.
<em>the function of epidermis is to protect the leaf
make it air tight
prevent water loss as it is waxy
also it is transparent and allows all light to enter...
chloroplast is required for carrying out process of photosynthesis...
as epidermis is not specialized to carry out photosynthesis... so it does not have any chloroplast...</em>
Answer: 1. True
2. Between six and right hours
Explanation:
1. Energy simply refers to the ability to do work. It's the strength that's required to be able to sustain a mental or physical activity.
It should be noted that fir positive interaction, energy requires physical activity, a balanced diet, adequate sleep, satisfying work and opportunities. Therefore, the statement is true.
2. Even though the hours of sleep that's used by people typically varies, adults generally need about six to eight hours of sleep.
I believe the answer is that a dimpled chin is controlled by a single gene with multiple alleles and height is controlled by many genes. Alleles are alternative forms of a gene, and they are responsible for differences in phenotypic expression of a given trait. A gene for which at least two alleles exist is said to be polymorphic.
