perform additional trials
Explanation:
i just took the test and got the answer right
Answer:
D. the nucleus contains the protons and neutrons which takes up most of the mass of the atom
Explanation:
The flowers will not grow as well because bacteria are needed to fix nitrogen
Numerous plants have symbiotic interactions with bacteria, which provide them with essential nutrients like nitrates. His flowers' growth will be limited and they can even perish if all the bacteria are gone.
<h3>What are Good bacterias ?</h3>
Friendly bacteria or good bacteria can help plants grow by helping the plants to obtain nutrients such as phosphorous and nitrogen, or by defending the plants from other microbes that can make them sick.
- Beneficial good bacteria for plants produce chemicals and hormones that stimulate growth. Beneficial bacteria help prevent infections from pathogens by coating the root surfaces and triggering svstemic disease resistance.
- By this way the use of bacteria killing chemical will all kill good bacteria which helps plant growth.

Answer:
The question lacks options, the options are:
A) 1 out of 16
B) 3 out of 16
C) 6 out of 16
D) 9 out of 16
The answer is 1 out of 16
Explanation:
This is a DIHYBRID cross because it involves two different genes coding for distinct traits. One of the traits will be dominant while the other recessive. Hence, parents that are purebred for opposite forms of the trait means that one parent is homozygous dominant while the other is homozygous recessive. When these two parents cross, they produce F1 offsprings that all possess the dominant trait but heterozygous/hybrids.
When these hybrids are self-crossed, they produce four different combinations of gametes which when crossed using a punnet square will result in F2 offsprings with a 9:3:3:1 phenotypic ratio according to Mendel's observation.
9 represents offsprings that are dominant for both traits
The two 3's represents offsprings that are recessive for one trait and dominant for the other respectively.
1 represents offsprings that are homozygous recessive for both traits.
Hence, 1 out of 16 offsprings will be homozygous recessive for both traits.
