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.
Answer:
its false, i can promise that

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.

why is ecology all about action and reaction?
___________________________________________________________
Answer:
The ecological approach emerged as a reaction to the lab approach, which was considered sanitized and perhaps too controlled. What can happen in a lab cannot necessarily happen outside and vice versa.

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.

a farmer wants to know which will allow his plants to produce the most food. he gave no fertilizer to 10 plants fertilizer a to 10 plants and fertilizer b to 10 plants. all of his plants were the same were planted in the same soil and we given the same amount if water after six weeks the farmer weighted the total amount of food produced by each group
Answer:
It depends on the optimum dosage of NPK.
Explanation:
The farmer gain more productivity from that type of fertilizer which have optimum dosage of nitrogen, phosphorus and potassium fertilizers because these three fertilizer needed by the plant in large quantity and having great contribution in the yield of plant so if ''fertilizer a'' has optimum dosage of these three nutrients so we can say that ''fertilizer a'' produces more food as compared to no fertilizer and ''fertilizer b'' whereas if ''fertilizer b'' has optimum dosage of these nutrients so ''fertilizer b'' produces more food.
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.

select the correct answer sickle cells  disease is a hereditary mutation that causes The red blood cells to the form decreasing their ability to carry oxygen based on the image what kind of mutation occurs to cause Sickel cell disease
Answer:
Sickle cell disease is due to a type of substitution mutation.
Explanation:
Sickle cell disease is a condition that is transmitted from parents to children in an autosomal recessive inheritance pattern. It is due to a mutation that is capable of altering the shape of the erythrocyte, as well as its ability to circulate and carry oxygen.
The mutation that occurs in sickle cell disease is due to an alteration in the β-chain of hemoglobin, caused by the substitution of thymine base by adenine in the DNA that determines it. As a result, valine replaces glutamic acid in the β-chain amino acid sequence, with the consequences described.
The other options are not correct because deletion, duplication and translocation correspond to chromosomal mutations, not responsible for sickle cell disease.PLEASE HELP ME OUT!
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 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.
If an organelle is selectively
permeable what can we infer
about its function?
MULTIPLE CHOICE
Answer:
What can be inferred about the function of a selectively permeable organelle is that organelle allows some molecules to pass trough (option C).
Explanation:
Selective permeability is a characteristic, present in the membranes, which allows the passage of some substances and prevents the passage of others, according to their structure.
An example of selective permeability is found in cell membranes, whose hydrophobic nature allows the passage of apolar molecules easily, limiting or preventing the passage of polar molecules and ions.
The other options are not correct because:
A. Not all molecules can pass through a semi-permeable organelle.
B. The semipermeable organelle does not prevent the passage of any substance.
C. Semi-permeable organelle does not allow the passage of large molecules easily.

Which function is performed by Earth's magnetic field?
O A. Charged particles from the sun are prevented from reaching Earth.
O B. Light radiation is converted to heat energy.
O C. Magnetic charges from space are prevented from reaching Earthis
O D. Utraviolet rays from the sun are prevented from reaching Earth.
surface.
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.
