what property makes phospholipids the ideal organic molecule to make up the cell membrane?

Answers

To perform these roles, the plasma membrane needs lipids, which make a semi-permeable barrier between the cell and its environment. It also needs proteins, which are involved in cross-membrane transport and cell communication, and carbohydrates (sugars and sugar chains), which decorate both the proteins and lipids and help cells recognize each other.

Explanation:

In males, the penis comes out of the cloaca into the female cloaca when mating. ... To finish off, turtle mating, if the female's egg is fertilized, results in, with some exceptions of course, the female laying an average of a 100 to 200 eggs.

All turtles lay their eggs on land, and none show parental care. Amidst this apparent uniformity, however, there is a variety of reproductive behaviours, ecologies, and physiologies.

The age at which turtles first reproduce varies from only a few years to perhaps as many as 50, with small species typically reaching sexual maturity sooner. Female false map turtles (Graptemys pseudogeographica) of the central United States, for example, are about 8 cm (3.2 inches) long and become sexually mature at two to three years.

Not all plant cells contain chloroplasts. What is the most likely reason for this?

Answers

Due to that they do not inhabit an area with sunlight.

Some plant cells such as those underground and deep in the ocean receive no sunlight. Chloroplasts use sunlight for photosynthesis, so the organelle would not be able to function making it useless.

Plant cells are defined as eukaryotic cells that are autotrophs and are capable of photosynthesizing. All plant cells do not contain chloroplasts as no sunlight reaches that area.

What is chloroplast?

Chloroplasts are the organelles of the plant cell constituted of the green-colored pigment called chlorophyll. This pigment is crucial for photosynthetic reactions as they capture the solar energy required to convert the reactants.

The plant parts like underground organs (root system) and inner stems lack chloroplast in their cells as no sunlight reaches that area, hence they are of no use in those systems and organs. They are not exposed to sunlight and cannot photosynthesize.

Therefore, all plant cells do not contain chloroplast as they do not undergo photosynthesis reactions.

Answers

Answer:

El statement that say Direct observation is the simplest and most effective method to determine population size is false.

Explanation:

Simple observation results in an inadequate method for estimating the size of a population, especially if it is very large and mobile. A simple and adequate method consists of counting individuals within a population, with some limitations.

Currently, in large populations, it is common to divide an area occupied by a population into quadrants, count individuals, and then extrapolate the data to the actual dimensions of the space occupied by that population.

Which characteristic is shared by telophase and anaphase?(1 point)


A The nuclear membrane dissolves.


B The two nuclei are formed.


C The sister chromatids move.


D The mitotic spindle is formed

Answers

Answer:

B The two nuclei are formed.

Explanation:

This question is describing the processes involved in MITOSIS, a kind of cellular division. Mitosis, however, takes place in steps

In both anaphase and telophase, the movement of sister chromatids takes place.  

• A phenomenon in which a single cell differentiates into two similar daughter cells is termed as mitosis.  

• Mitosis takes place with precise steps and regulation.  

• The dissolving of the nuclear membrane takes place in the prophase phase of mitosis.  

• The formation of two nuclei takes place at the telophase stage of mitosis.  

• The formation of mitotic spindle takes place at the metaphase stage of the mitosis.  

• In the anaphase, the sister chromatids or the chromosomes are pulled towards the opposite poles, and in telophase the sister chromatids or the chromosomes arrive at the opposite poles, thus, in both anaphase and telophase, the movement of sister chromatids is taking place.  

Thus, the correct answer is option C, that is, the sister chromatids move.

Answer:

D. Ultraviolet rays from the sun are prevented from reaching Earth.

surface.

Explanation:

What little is known is that the Earth's magnetic field creates the so-called "magnetic shield" that provides protection against some other dangerous forms of radiation, namely cosmic rays and solar wind.

While there is no danger of losing the Earth's gravitational field, the Earth's magnetic field is declining faster than any other geophysical phenomenon. This continuous loss of the Earth's magnetic field, and the associated increase in harmful radiation, are beyond human control.
