Answer:
A
Explanation:
Primary productivity, in ecology, the rate at which energy is converted to organic substances by photosynthetic producers.
describe what happens when a chlorophyll a molecule absorbs a photon
what happens when chlorophyll molecule absorbs light: photosynthesis begins. it becomes excited. This energy passes through other chlorophyll molecules, and into the reaction center of Photosystem II (Electron transport chain). OR the molecules are raised to a higher energy level.

Life cycles recycle matter and help to create balance on Earth because
Producers gain energy from the sun. Consumers gain energy from producers. Decomposers gain energy from dead consumers and
recycle it back to producers.
Living organisms are dependent on other living organisms to survive.
Producers make their own food. Consumers gain energy from producers. Decomposers break down dead matter into essential
nutrients that are then reused by producers.
Answer:Living organisms are dependent on other living organisms to survive

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

The following cells is the ___ stage of ___
Answer: Telophase, mitosis
Explanation:
The following cells is the telophase stage of mitosis. We can see that in the picture because we can see parts such as the Contractile ring(which is in the middle), Complete nuclear envelope, Decondensed chromosomes, and Centrosome.
This is considered as the final or also called the fifth process in which the cell is getting separated and it is duplicating genetic material that is carried in the nucleus.

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
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.

Please select the best answer from the choices provided
OT
F
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.

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.
