What are the correct order of steps of binary fission from first to last?
Answer:
Explanation:
Step 1- Replication of DNA
The bacterium uncoils and replicates its chromosome, essentially doubling its content.
Step 2- Growth of a Cell
After copying the chromosome, the bacterium starts to grow larger in preparation for binary fissions. It is followed by an increase in cytoplasm volume as well as an increase in the number of organelles. Another prominent trait of this stage is that the two strands migrate to opposite poles of the cell.
Step 3-Segregation of DNA
The cell elongates with a septum forming at the middle. The two chromosomes are also separated in this phase.
Step 4- Splitting of Cells
A new cell wall is formed at this phase, and the cell splits at the centre, dividing the parent cell into two new daughter cells. Each of the daughter cells contains a copy of the nuclear materials as necessary organelles.
Binary fission begins with the replication of DNA. The DNA is copied. The cell elongates. The DNA is pulled toward both ends of the cell. A new septum is formed. Cytokinesis occurs. The septum is completed as a cell wall. The cells are divided in two.
The steps of binary fission can also be explained with the help of amoeba as an example.
First, an amoeba divides into two nuclei and replicates. The nuclei divide and migrate to opposite sides of the parent cell. Then, the cell produces proteins and nutrients to prepare for binary fission, in which it divides and forms two daughter cells.

The allele for brown fur in mice (B) is dominant over the allele for white fur (b).
The fur color of one mouse is represented by Bb.
What is the genotype of this mouse?
What is the phenotype of this mouse?
Genotype is if it is dominant or recessive, and phenotype are the physical characteristics of the fur.
Genotype:
Since it has a capital letter, it is dominant, and since both letters are not the same case, it is heterozygous dominant.
Phenotype:
Since dominant traits mask recessive, it is brown fur.
Answer:
the genotype is Bb
and the phenotype is brown

Answer:
Wind farms
Explanation:
There is a species of beetle that has two different color phases. Some have dark, purplish shells with green spots on them; others (same species) have greenish shells with purple spots on them, and there are other varieties that are somewhere in between. The beetles feed on the garden plants and the birds in the area feed on the beetles. When Mr. Jones bought his 200 acre farm, most of his farm was overgrown with an invasive vine that had purple stems and leaves. As he set to work removing these vines so he could farm the land he found many of these beetles on his land. Most of them were the purple color phase, with the occasional green beetle here and there. After several years and lots of hard work he had removed all of the purple vines and replaced them with green soybeans and corn plants. By this time, when he was working in his fields, he noticed that he still saw lots of the beetles, but very few of them were purple. Instead, most of them were the green color phase.

What are the key features of a tundra?
A. cold winter, thin acidic soil, evergreen trees
B. many evergreen trees, short moist summers, long snowy winters
C. long cool summers, short dark winters, migrating animals
D. treeless, permafrost, cold dark winters
Answer:
D. treeless, permafrost, cold dark winters
Explanation:
The correct answer would be D
Tundra is a habitat in which tree growth is hampered by cold temperatures and short growing seasons. Therefore, option (D) is correct.
What is a tundra?The freezing temperatures and short growing seasons of a tundra biome make it difficult for trees to develop in this sort of ecosystem.
Most of the time, it is cold, but in the summer, it can get quite warm. The winters on the tundra are long, dark, and very cold. For six to ten months of the year, temperatures are below 0 degrees Celsius. Because the temperatures are so low, there is a layer of frost below the surface. This is a layer of frozen ground.
Arctic tundra is found above the Arctic Circle in Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, or in Antarctica. Alpine tundra are high on mountains where nightly temperatures are below freezing.
Therefore, option (D) is correct.
