Answer:

Biodiversity is very essential to the health of an ecosystem.

Explanation:

Biodiversity is essential to the health of an ecosystem because biodiversity provides functioning ecosystems that provides oxygen, clean air, clean water, pollination of plants, pest control, wastewater treatment and many ecosystem services. The change of temperature of the environment greatly affect the organisms because the organisms needs specific environment for growth and development. Habitat change, climate change, invasive species, overexploitation, and pollution are the factors that affect biodiversity. These factors causes increase or decrease in the biodiversity of the ecosystem.

Answer:

Sólido, líquido, gas y plasma.

Explicación:

Materia son las sustancias que ocupan espacio y tienen peso. Hay cuatro estados de la materia, es decir, sólido, líquido, gas y plasma. Todos los materiales presentes en este universo en estos cuatro estados. Los estados de la materia cambian con el aumento o la disminución de la temperatura del material. si la materia sólida se calienta, se derrite y cambia a estado líquido y luego gaseoso mientras que, por otro lado, la temperatura decreciente conduce a la condensación y congelación de la materia que causa el cambio de estado gaseoso a líquido y sólido. El plasma está formado por un gas de iones, átomos o moléculas.

ANSWER: A NATURAL SELECTION.

EXPLANATION:

When allele has direct effects on the organism and the environment, it is termed natural selection. It either affects an organism positively by causing more DNA reproduction, leading to the increase in allele’s frequency, or negatively by decreasing it .

However, this shouldn't be mistakened for genetic drift, where allele increase or decrease is established in the random organisms that survived.

Answer:

Amoxicillin

Explanation:

Amoxicillin (Amoxil) is a commonly prescribed antibiotic which can cure acute sinus infections. Amoxicillin-clavulanate (Augmentin) is often prescribed by the doctor for a bacterial sinus infection. Take antibiotics as long as your doctor has prescribed in order to get rid completely from the infection and in order to reduce the chances of infection up to zero. They may be taken from 3 to 28 days depending on the time of antibiotic for sinus infection.

Answer:

Protista. hope this helps!!! (my answer might be wrong)

Answer:

The answer is E.

Explanation:

An anabolic reaction is one that involves the building of complex substances from simple ones and it uses up energy. Photosynthesis is an anabolic reaction because It requires energy.

A catabolic reaction is one that involves the breakdown of complex substances into simpler ones and in the process energy is released. Cellular respiration is catabolic because energy is released during this process.

Answer:

The person is correct

Explanation:

I got it right

Answer:

no the carrying capacity of an ecosystem can't change

it is literally impossible hope it helps you have a good day please mark me as brain list

Answer:

No carrying capacity of an ecosystem doesn't change.

Explanation:

Each organism that lives there will have a different carrying capacity, one that interacts with everything around it. If the climate changes and the resources a particular animal needs for food drop, for example, that change in carrying capacity for one species will affect other populations in the area.

Answer:

Our bodies consist of a number of biological systems that carry out specific functions necessary for everyday living. The job of the circulatory system is to move blood, nutrients, oxygen, carbon dioxide, and hormones, around the body. It consists of the heart, blood, blood vessels,arteries and veins.

Explanation:

Answer:

why do cells divide is mitosis

mitosis is understood to involve five phases

how many daughter cells produced in mitosis two

how many daughter cells produced in meiosis four daughter cells

A condition in which every cell in the body has an extra set of chromosomes is not compatible with life. In some cases, a change in the number of chromosomes occurs only in certain cells. When an individual's cells differ in their chromosomal makeup, it is known as chromosomal mosaicism .

HOPE  THIS helps

Explanation:

Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies - or 'replicates' - its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.

[tex]\Large{\textbf{Mitosis:}}[/tex]

[tex]\Large{\textbf{Meiosis:}[/tex]

       The stages of Meiosis 1 are,

                                            (a) Prophase (which is sub-divided into 5 more  stages which are Leptotene, Zygotene, Pachytene, Diplotene and Diakinesis)

                                             (b) Metaphase,

                                             (c) Anaphase,  

                                             (d) Telophase.

        The Stages of Meiosis 2 are, Prophase, Metaphase, Telophase and Anaphase which are same as mitosis.

     3. In meiosis, Cell divides twice.

     4. In meiosis, 4 daughter cells are produced.

     5. Yes, the chromosomal number in mitosis is reduced to half than normal i.e. 23

     6. In meiosis, the final result is 4 haploid cells. If meiosis occurs in male then these haploid cells will be called sperms, if it occurs in female then they are called Ova(egg).

Just to give you some insight knowledge of Meiosis Im adding some extra points

[tex]\Huge\textbf{Meiosis:}[/tex]

Meiosis is a special type of cell division, which occurs only in the germ cells during the process of development and maturation to form gametes. It consists of two successive cell divisions,

Meiosis 1 : First meiotic division, that reduces the NUMBER of chromosomes i.e. the parent cell is diploid(46 Chromosomes) and the daughter cells are haploid(23 Chromosome). It also causes genetic variation in the haploid by cross linkage.

Meiosis 2 : Second meiotic division (Meiosis II) starts with two haploid parent cells and ends with four haploid daughter cells. Meiosis 2 like Meiosis 1, does not reduce the NUMBER OF CHROMOSOME that means the forming 4 daughter cells are haploid and their number of chromosome remains the same as the parent. BUT Haploid cells that go into the meiosis 2 have MORE AMOUNT OF CHROMOSOME THAN USUAL, thus MEIOSIS 2 REDUCES the amount of chromosome rather than the number of chromosome.

The DNA of the primitive germs cells is replicated prior to the meiosis 1 only and there is no replication of DNA before Meiosis 2. The four final cells reulting from the two meiotic divisions are not only haploid(i.e. containing 23 chromosome) but they are also containing 1n amount of DNA so that when the gametes fuse together forming a zygote, both the amount and number of chromosome and DNA remains SAME.

[tex]\Large\text{Why is Meiosis Important?}[/tex]

Meiosis is essential for the sexual reproduction of eukaryotic organisms because it enables genetic diversity through recombination, and the repair of genetic defects.

It contributes in genetic reassorment which ensures the genetic diversity in the offsprings. The genetic reassortment takes place by following two mechanisms:

Answer:

To summarize, two things determine the traits an organism has: its genotype and the dominance or recessiveness of the alleles it has. Some traits, like flower color in peas, are controlled by a single gene, but ultimately many if not most traits in an organism are controlled by more than one gene

Explanation:

Answer:100 percent

Explanation: This is because if both P plants are heterozygous both of them are caring an equal amount of genes hence they have and are 100% P plant heterozygous

Answer: The energy transformation that takes place during cellular respiration is the conversion of glucose (chemical energy) to another form of compound with high energy bonds (adenosine triphosphate) that can be readily used by the body. All energy on Earth comes from the sun.
