The number of atoms that remains at the said time is 3.76 * 10^11 atoms of Cl-36 and 2.62 * 10^12 atoms of Ar-36.
What is the half life?The term half life is used to explain the time taken for only half the number of radioactive atoms to remain.
Given that;
No = 3 * 10^12 atoms
t1/2 = 3.01 8 10^5 years
t = 9.03 * 10^5 years
Thus;
k = 0.693/3.01 * 10^5
=2.3 * 10^-6 year-1
Now;
N=Noe^-kt
N = 3 * 10^12e^(2.3 * 10^-6 * 9.03 * 10^5)
N = 3.76 * 10^11 atoms

select the incorrect association amoeboid cell - digestion, collar cell - water current, epidermal cell - covering, spicule cell - reproduction
Spicules is the skeletal structures which occur in most sponges. They provide structural support, as well as determent against predators. Large spicules, visible to the bare eye are called as megascleres, while smaller, microscopic ones are called as microscleres. Spicule cell - reproduction is the incorrect option.
amoeboid cell - digestion
What is amoeboid cell?Amoeboid cells are the that have capacity to change shape due to the parts of the skeleton of the cell called cytoskeleton and plasma-gel which changes the consistency of the cell's cytoplasm. Amoeboid cells use a pseudopodia, or false foot, to move forward. They carry-out phagocytosis, which is to eat or ingest other cells.
collar cell - water current
The collar cells serve two functions. Firstly, they beat their flagella back and forth to force water through the sponge. The water brings in nutrients and oxygen, while it carries out waste and carbon dioxide. Second, the sticky collars of the collar cells pick up tiny bits of food brought in with the water.
epidermal cell - covering.
The epidermis and its waxy cuticle provide a protective barrier against mechanical injury, water loss, and infection.

A. Lymphocyte
OB. Neutrophil
OC. Platelet
O D. Macrophage
Answer:
Platelets
Explanation:
________________________________________________________
Platelets are not a type of white blood cell because they only help treat wounds and slow down/stop you from bleeding.
they don't remove any germs. they only help treat your wound.
________________________________________________________
Hope this helped :)
This type of blood cell is not a type of white blood cell is C. Platelet.
What is a platelet?Platelets are not a type of white blood cell. They are actually small, colorless cell fragments that are involved in the clotting process of blood. White blood cells, on the other hand, include various types such as lymphocytes, neutrophils, and macrophages, which play important roles in the immune response and defense against infections.
Platelets, also known as thrombocytes, are small cell fragments that circulate in the blood. They are formed in the bone marrow along with other blood cells. Platelets play a crucial role in hemostasis, which is the process of blood clotting to prevent excessive bleeding.
When there is an injury or damage to blood vessels, platelets are activated and aggregate at the site of injury. They form a plug to seal the damaged blood vessel and initiate the clotting cascade, which leads to the formation of a blood clot.
The correct answer is C. Platelet.

9. A protein molecule which is denatured, has
a. split into smaller molecules
c. Changed its shape
b. combined with another molecule d. been diluted
Answer: B. combined with another molecule
Explanation:
i just took the test
Proteins are macromolecules composed of amino acid chains joined through peptide bonds. A denatured protein molecule has changed its shape. Thus, option c is correct.
What is protein denaturation?Protein denaturation is a process where the proteins under unfavorable conditions like temperature, chemicals, and pressure result in an alteration in their functions.
The basic structural organization of the proteins contains primary, secondary, and tertiary formation that gets altered at high temperatures resulting in the breaking of the covalent bonds and disruption of the amino acid chain.
This results in the protein breaking and forming the primary structure that leads to alteration of the shape and conformation. This change results in loss of the function and activity of the protein.
Therefore, option c. the denatured proteins result in alteration in shape.

Several bird species feed in a certain species of tree. each bird species feeds in a different part of the tree. which factor are the species of birds responding to in the environment?
a.) symbiosis
b.) competition
c.) parasitism
d.) omnivores
Competition factor are the species of birds responding to in the environment. Thus, the correct option is B.
What is competition?If numerous bird species eat on the same tree species, there will be fierce competition for food. As a result of the competition, each species will seek out a certain portion of the plant to feed on, most likely the part of the plant where it will be easiest to outcompete the competitors for food.
As a result, we may deduce that the right response is "They have evolved to diverse niches as a result of competition."

Answer:
the flat horizontal lines indicate phase change
Explanation:
As the substance changes phase from solid to liquid and liquid to gas, the temperature remains contant due to latent heat energy.
Energy is being used to break the intermolecular bonds during phase change, therefore there is no change in temperature.
Substance A has a specific heat capacity of 0.452 J/g℃, Substance B has a specific heat capacity of 2.64 J/g℃. If an equal mass of both substances at room temperature was placed in a heated room, which substance would you expect to heat up faster?
Substance A or B?
The substance would you expect to heat up faster is Substance A, which has a specific heat capacity of 0.452 J/g℃.
What is specific heat capacity?The specific heat capacity is the amount of heat necessary to elevate 1 degree 1 kg of the substance. Its unity is J/gºC. We can calculate the heat that changes the temperature of a substance by the equation:
Q = mcΔT
Where Q is the heat, m is the mass, c is the specific heat capacity, and ΔT is the change in the temperature.
Thus, Substance A, has a specific heat capacity of 0.452 J/g℃.

A calorie is a measure of energy. Assume that there are 1000 calories of plants in a chamber. If grasshoppers (a plant eating insect) eat all of the plants and a bird eats all of the grasshoppers, how many calories did the bird actually absorb if only 10% of the energy is transferred between each level.
Only 10 calories did the bird actually absorb when there is a total of 1000 calories were stored in a plant chamber.
What is Calorie?A calorie may be defined as a unit of energy that we get from food products and burn during a physical workout.
According to the 10% law given by Lindeman, if a plant chamber consists of 1000 cal., the amount of energy transferred to herbivores is 10% of 1000 which is 100 calories.
Similarly, the 10% of 100 cal., gets transferred to the next trophic level which is carnivores or secondary consumers. The 10% of 100 is 10 calories.
Therefore, only 10 calories did the bird actually absorb when there is a total of 1000 calories were stored in a plant chamber.
