Describe the organism (physical appearance, habitat, function, history, etc.). Draw or find a graphic that represents your organism. Detail the organism's method of reproduction: asexual or sexual type of gametes method of fertilization advantages and disadvantages of the reproduction type Note: your description and detail of the organisms should be at least 300 words.
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.

how are photosynthesis and cellular respiration is important for our survival?
Answer: Photosynthesis and cellular respiration is important for our survival because our food chain is all reliant on plants. photosynthesis is how plants get energy and food from the sun. whether you eat plants or meat from farm animals, that energy all goes back to plants and the process of photosynthesis.

(Science) Determine the number of atoms of each element that makes the following compound: CaCl2. Be sure to select zero if an element is not present in the compound. Carbon:___ Calcium:____ Chloride:____Hydrogen:____ Oxygen:____
Answer:
Carbon:0
Calcium:1
Chloride:2
Hydrogen:0
Oxygen:0
Explanation:
Ca is calcium and there is only one in the compound due to no subscripts. Cl is chloride with a subscript of 2, meaning there are 2 atoms of that element in this compound.
Answer:
Calcium Chloride
Explanation:
Doing this test rn but if you still need the answer here
Carbon atoms: 0
Calcium Atoms: 1
Chloride Atoms: 2
Hydrogen Atoms: 0

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.

Graph A above demonstrates that the rate of photosynthesis
Adecreases in response to increasing light intensity
B)continues to increase exponentially (continuously) in response to
increasing light intensity
C)increases in response to increasing light intensity but only to a certain
point
D)is not affected by light intensity
C)increases in response to increasing light intensity but only to a certain
point
The intensity of photosyntheis increases until the intensity of light reaches 50000 luxes after 100000 luxes the rate of photosynthesis will decrease because the intense light damages the tissues.
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.

Direct observation is the simplest and most effective method to determine population size
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.

O C. Magnetic charges from space are prevented from reaching Earthis
O D. Utraviolet rays from the sun are prevented from reaching Earth.

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.

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