an enzyme catalyses only one reaction explain why
Answer
Enzymes are proteins, which have a specific 3D tertiary structure, with a specifically shaped active site. The active site can only bind one substrate to form an enzyme-substrate complex, so can therefore only catalyse one reaction.
The purpose of the light-dependent reactions of photosynthesis is to -
a

b
produce sugars
c

Fraternal twins, while conceived at the same time, are not genetically identical.
Which statement best explains why these siblings are genetically different from each other
Answer:
Fraternal twins are also called dizygotic twins. And the difference between fraternal and identical twins is that fraternal twins derive from two different eggs. Fraternal twins may be the same gender, they may have many of the same characteristics, but also may be very different from each other and, in fact, share half of their genes just like their sisters and brothers. It's important to recognize that the difference between fraternal twins and monozygotic, or identical twins, is that monozygotic twins result from the fertilization of a single egg with a single sperm and then during the embryonic development, or during the cell splits, those massive eggs split into two individuals, which later develop into two offspring.

In mitosis the daughter cells are identical to the parent cell. How do the cells produced during meiosis differ from those produced from mitosis
Answer:
The cells produced during mitosis are identical but cells produced in meiosis are different.
Explanation:
This is because in mitosis, there is no crossing over, but crossing over occur in meiosis. During crossing over, there is swapping of the genetic material.

Answer:
polysaccharide
Explanation:
why is the human brain unique
Answer:
Like with fingerprints, no two people have the same brain anatomy, a study has shown. This uniqueness is the result of a combination of genetic factors and individual life experiences. Like with fingerprints, no two people have the same brain anatomy, a study by researchers of the University of Zurich has shown.

you could chose to describe the first graph as any of the following phrases:
‘curved graph’
‘intercept on y-axis’
‘as x increases, y increases’,
‘y increases slowly at first, then more rapidly, then slows down again’ and ‘reaches a maximum level’.

Which of the following is a possible consequence of solid pollutants in a lake or river?
Build-up of garbage in freshwater
Quick drop in dissolved oxygen
Decrease in algae colonies
Sudden hypoxic waters
Answer:
B.) Quick drop in dissolved oxygen
Explanation:
High level of total suspended solids will increase water temperatures and decrease dissolved oxygen levels. This occurs because the pollutants absorb more heat from solar radiation than water molecules.

The suncoast tree of northwest Africa is known for 2 traits that are said to show simple dominance. The 2 traits are height and bark color. In height, tall is dominant to short, and in bark color blue is dominant to purple. What would the genotypes be of a suncoast tree that is pure bred purple and tall and a suncoast tree that is heterozygous for both traits?
A. bbTT X BbTt
B. BBtt X BBTT
C. bbtt X bbtt
D. BbTt X BbTt
The genotypes would be bbTT X BbTt
Assuming that bark color is represented by B (b) allele and height is represented by T (t) allele.
Since the traits show simple dominance: blue (B) of dominant over purple (b) and tall (T) is dominant over short (t)
The genotype of a tree that is purebred purple (bb) and tall (TT) would be bbTTThe genotype of a tree that is heterozygous for both trait would be BbTtThus, the cross would be bbTT x BbTtMore on genotypes can be found here: https://brainly.com/question/20730322?referrer=searchResults
11 Apply If you have a cold that causes congestion in your sinuses, how
might that affect your sense of smell? Support your claim with evidence.
Answer:
If there's a blockage of this channel, like when you have a stuffy nose due to the flu or a cold, odors can't get to the sensory cells the smells stimulate. This results in you losing a lot of your ability to taste the flavor of food. In this manner, your senses of taste and smell work closely together.
Answer:
It will affect your smell because you can have a lot of snot in your nose and your nose will be stopped up with all that stuff.
(SCIENCE) which of these statements about heating up water on earths surface is true? water heats up faster than land water heats up by conduction from Earth
PLEASE HELP!!!!
Answer:
Water heats up to a lower temperature than land.
Explanation:
Because water has a much higher heat capacity, or specific heat, than do sands, soils or other materials, for a given amount of solar irradiation , water temperature will increase less than land temperature.
