Answer:

C i did this in ed not to long ago

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. Tanto en los métodos citotóxicos como en los citotóxicos, ambos causan toxicidad en la célula que inhibe el crecimiento y la estructura normales de la célula.

Answer:

The shape in V of the vomerine teeth is useful to hook the prey and hold it until the frog can swallow it.  

Explanation:  

In frogs, we can distinguish maxillary teeth, premaxillary teeth, and Vomerine teeth.

Vomerine teeth are projections of the vomer bone, located in the anterior part of the paladar and between the internal nares.

Vomerine teeth are specialized structures that help frogs catch and hold their prey. They are not involved in chewing or killing (frogs swallow the entire prey alive), just holding the creature before swallowing it.

These projections are covered by soft tissue. When the frog catches the prey, presses the tongue against the roof of your mouth. The vomerine teeth hook the prey and prevent it from slipping or wandering away.

The shape in V of the vomerine teeth is useful to hook the prey and hold it until the frog can swallow it.

Answer:

Genes!!

Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.

Answer:

Option C is the correct one

Explanation:

Exponential population growth: When resources are unlimited, populations exhibit exponential growth, resulting in a J-shaped curve. When resources are limited, populations exhibit logistic growth. In logistic growth, population expansion decreases as resources become scarce.

Answer:

Populations have the potential to grow exponentially when resources are abundant.

New seafloor material is formed at places in Earth's crust where, one tectonic plate slides beneath and is forced downward. Thus, option 2 is correct.

The word tectonic Plates was derived from Latin word tectonicus which means pertaining to building. Scientific theory considers that there are  a number of large tectonic plates on earth, Which has been moving since  3.4 billion years ago.

Tectonic plates are consist of oceanic and continental lithosphere. Earths  lithosphere has greater mechanical strength therefore, plates are able to move.

Therefore, option 2 is correct.

Answer:

1. Translation

2. Cytoplasm

3. Ribosome

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.

Answer:

The correct answer is - magnitude.

Explanation:

The earthquake is measure by the Richter scale in the unit of magnitude. It is the size of the earthquake in the length into the width and the slip. Magnitude is nothing but the distance or the power or extent of the earthquake.

There are different energy at different measures of magnitude on the Richter scale. Magnitude of 7.2 releases 30 times more energy than the energy releases by 6.2 magnitudes.

Answer:c

Explanation:

Answer:

The correct answer is the option B: Fluid; Crystallized.

Explanation:

To begin with, in 1963 the psychologist Raymond Cattell introduced the concepts of both Fluid intelligence and Crystallized intelligence in where he explains that both are derived of the General intelligence. The first one refers to the ability of solve novel reasoning problems and is related to the capacity of important skills such as comprehension, learning and more. And the second one, the Crystallized intelligence refers to the ability of learn procedures and more technical knowledge about certain topics reflecting the effects of experience about that.

Explanation:

Answer:

Rivers change course, mountains rise and continents drift.

Explanation:

Rivers change course, mountains rise and continents drift are the geographic barriers that have led to the flinch speciation in the Galapagos because these barriers separated finch species from one another. Due to these geographic barriers, finch species have different body structure and features. These geographic barriers prevent two finch species from interbreeding with one another which leads to flinch speciation.

One letter from each parent are combined to create a genotype of one possible offspring. Example: G (from one parent) + g (from the other parent) = Gg (genotype of offspring)

Capital letters are dominant and lowercase letters are recessive

Dominant traits mask recessive ones so when the genotype of the offspring is Gg, it will be green because green is dominant over yellow

Answer:

The Meiosis Cell Cycle

Explanation:

Cell cycle is the process if cell division. The end product of cell cycle is two genetically identical daughters cells produced by cell division.

Cell cycle is the process occurring through different stages by which a cell divides to form its daughter cells. Various enzymes have significant roles in cell cycle.

A large number of DNAs in the chromosome of a cell undergo division where, the double stranded DNA separate and and each strand forms two new DNAs.

Therefore, at the end of a cell cycle through proper cell division, two genetically identical daughters cells are produced.
