<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2>

1- Fire uses the energy, The heat is required, it is the part of the chemical reaction. Heat reacts with the fuel and oxygen to ignite it.

2- Bacteria as the decomposers gets rid of the wastes. It breaks down the organic material such as the remains of dead organisms.

3- Fire grows and develops, The fire has different stages. If its not controlled in its initial stages it could grow and develop into really big destruction.

4- Bacteria can sense and respond to stimuli. There is phototactic and chemotactic movement found in bacteria.

5- Bacteria has ways to protect itself from har.sh environment. They can form colony and work together against the changes, also they can form the hard cyst to protect themselves from the unfavorable conditions.

6- Bacteria reproduces, It has different ways of reproduction i.e. Trans.duction, Transf.ormation, conju.gation.

7- Wrist.watch have a def.ined boun.dary as it is not a living thing it can't gr.ow, it does not have 8 chara.cteristics of li.fe.

8- Wrist.watch has internal organization which help them to carry out basic functions

9- Algae are made of more than one cells

8. In a population of beetles, there is a gene for color with two codominant alleles. The allele R leads to red beetles and the

Eddi Din [679]

Answer:

The genotypic frequency = 1:1

The phenotypic frequency = 1:1

Explanation:

Given that:

The allele → R = Red beetles

The allele → B = Blue beetles

Since the gene color shows a codominant allele

The Red Beetle = RR

The blue beetles will be = BB

The heterozygous beetle will be = RB

∴

The punnet square showing the crossing of RB × RR is:

R B

R RR RB

The result shows that we have two red beetles and two heterozygous beetles.

Hence;

The genotypic frequency = 1:1

The phenotypic frequency = 1:1

At the end of meiosis i, there are two haploid cells, each with two sister chromatids per chromosome. True or false?.

jok3333 [9.3K]

True.

At the end of meiosis I, there are two haploid cells.

<h3>What is the process of meiosis I?</h3>

Meiosis I refers to the initial nuclear division that takes place when gametes are formed. Due to the fact that the resulting cells have half as many chromosomes as the parent cell, it is also referred to as the reduction division. Prophase I, Metaphase I, Anaphase I, and Telophase I are the four phases that make up Meiosis I.

Prophase I:

The chromosomes condense during prophase I and become apparent inside the nucleus. Following this chromosomal condensation, each chromosome pair's members align adjacent to one another and are referred to as homologous chromosomes because of their identical size and gene content.

At this stage, a mechanism known as synaptic attachment occurs between the two chromosomes in each pair along their lengths. Then, while the homologous chromosomes are tightly coupled, the individuals within each pair cross over, also known as recombination, to exchange neighboring pieces of DNA. The nuclear membrane eventually starts to deteriorate after the conclusion of prophase I.

Metaphase I:

Microtubules leave the spindle at the beginning of metaphase I and join the kinetochore close to the centromere of each chromosome. In specifically, microtubules from one spindle side bind to one chromosome while those from the other spindle side adhere to the other chromosome in each homologous pair. The chromosomal pairs subsequently align themselves along the equator of the cell, forming the metaphase plate, with the assistance of these microtubules.

Anaphase I:

The homologous chromosomes are separated during anaphase I by the disintegration and contraction of the microtubules, which causes the two chromosomes in each pair to be drawn toward the opposite ends of the cell. Because of this division, each daughter cell that emerges from meiosis I will have half as many chromosomes following interphase as the original parent cell. Additionally, each chromosome's sister chromatid still has a connection.

Telophase I:

In telophase I, the cytoplasm organizes and separates into two as the new chromosomes approach the spindle. Now there are two cells, and each one has half as many chromosomes as its parent cell did. The recombination that took place during prophase I also caused the two daughter cells to not be genetically identical to one another.
