Answers

Answer:

Ambos son similares en sus acciones.

Explicación:

La principal diferencia que existe entre los métodos citotóxicos y citotóxicos es que los citotóxicos son las sustancias que envenenan la célula, mientras que los métodos citotóxicos son las formas de toxicidad celular. Tanto los métodos citotóxicos como los citotóxicos son similares en su acción porque tanto los métodos citotóxicos como los citotóxicos dañan la célula.

Would it be justified to call Kreb's Cycle the central wheel of metabolism? Why? Provide two specific pieces of evidence to support your answer.

Answers

Answer:

Yes.

Explanation:

Kreb's Cycle is considered as the central wheel of metabolism because the fuel molecules are oxidized ultimately within the Krebs Cycle and its intermediates are used for various biosynthetic pathways. The main function of the Kreb's cycle is to produce electron carriers that can be used in the cellular respiration for producing energy molecules in the form of ATP. without Krebs's cycle, the cell produces only two ATP molecules which very low.

presence of the placenta (mammals)

Explanation:

Cat and dogs are two species that belong to the group of placental mammals (class Mammalia). Some phenotypic traits that are exclusive of mammal species include, among others, mammary glands, presence of hair or fur, sweat glands, specialized teeth, etc. A phylogenetic tree is a representation of the evolutionary relationships among different groups/taxa. Moreover, cats and dogs represent two different species of placental mammals, which are characterized by the presence of the placenta (an organ that facilitates the exchange of nutrients during gestation). In this case, the remaining two branches in the phylogenetic tree (branches from left to right) separate from more closely related to less closely related taxa that diverged from the same ancestral node.

What is Stars?

A star is the most well-known celestial object and the main building block of galaxies. The age, distribution, and composition of a galaxy's stars can be used to determine the galaxy's history, dynamics, and evolution.

In addition, stars generate and disperse heavy elements like carbon, nitrogen, and oxygen, and their characteristics are strongly tied to those of any planetary systems that may develop around them.

The study of the origin, development, and death of stars is thus at the heart of astronomy.

Therefore, Stars are hot objects and give off heat and light. Composition and exact mass are the things about stars.

What are Gametes cells?

Answers

Answer:

I think Gametes are mature male or female reproductive cells that fuse together resulting in a zygote during sexual fertilization. The key difference between somatic cells and gametes depends on the ploidy of the genome. Somatic cells consist of diploid (2n) genome while gametes consist of a haploid (n) genome.

Hope it help you!:)

Answer: Gametes are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. ... In contrast, each egg cell, or ovum, is relatively large and non-motile.

Answers

Answer:

1. Translation

2. Cytoplasm

Explanation:

Translation is a process whereby the cell uses a mRNA template to produce an amino acid sequence (protein). It is the second stage of gene expression in living organisms.

Translation occurs in the CYTOPLASM of a cell with the help of an organelle called RIBOSOME. The ribosome attaches to the mRNA molecule in the cytoplasm to initiate the process of translation.
