Photosynthesis is an endergonic reaction. Why?

Biology
2 answers:
DochEvi [55]3 years ago

Photosynthesis is an endergonic reaction because the plants are absorbing light energy. It's not heat energy but it's light energy. So they're absorbing that energy to make new stuff. Photosynthesis cannot happen without adding energy.

Photosynthesis is endergonic (needing energy) because in the process OF photosynthesis, these plants use sunlight and carbon dioxide and water to make glucose which is sugar. It's taking substances to make the energy it needs.

In a population of plants, the allele for long stems (S) is completely dominant over the allele for short stems (s). If 35% of t
Sergio [31]

Answer:

The correct answer would be 48 percent.

It can be solved by using the Hardy-Weinberg equation.

p² +  2pq+ q²  = 1

p + q = 1

where, p² represents homozygous dominant's frequency that is, SS in this case,

q² represents homozygous recessive's frequency that is, ss in this case,

2pq represents heterozygous dominant's frequency that is, Ss in this case.

p represents dominant allele's frequency and q represents the recessive allele's frequency.

Now, the percentage of homozygous recessive or short stems is 35%. Therefore, the frequency of homozygous recessive would be 0.35.

Thus, the value of q² = 0.35

So, q = \sqrt{0.35} = 0.59 which is approximately equals to 0.6.

As p + q = 1 so, q = 1 - 0.6 = 0.4

The frequency of heterozygous (Ss) = 2pq = 2(0.6)(0.4) = 0.48

Hence, the frequency of heterozygous would be 48 percent.

Describe how Darwin theory of evolution by natural selection can explain the spread of antibiotics resistant microorganisms like
Sunny_sXe [5.5K]
Darwin's theory of evolution by natural selection can explain how antibiotics are becoming defective because the bacteria that is trying to be fought off might have had a mutation making it more likely to survive. Once that surviving bacteria makes offspring most of the first generation will die from the antibiotic but soon all of their offspring will produce a resistance to that antibiotic.

What does it mean that a hypothesis must be testable? can a hypothesis be proven unquestionably true? why or why not?
katen-ka-za [31]
A testable hypothesis must be just that--testable. You must be able to provide evidence that your hypothesis can be proven true in order for it to be considered accurate enough for future use among scientists. This can be done through repeated experimentation.

true.

Explanation:

all the somatic cells of an organism have same number of chromosomes while gametes are haploid and have half number of chromosomes. so gametes are different from somatic cells.
