Answer:

What the scientist is doing incorrectly is disposing of a chemical or biological waste in the common sewer.

Explanation:

One of the most important biosecurity measures is the proper disposal of chemical and biological waste. What the shown scientist is doing incorrectly is disposing of potentially harmful substances in a normal sewer.

The main thing that must be done to maintain a safe laboratory is to perform proper disposal of chemical or biological waste, which must be placed in airtight containers and transported to a location for safe disposal.

Following these procedures is important to avoid chemical or biological contamination of both the environment and people.

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.

Nutrients

Heterosporous plants are the ones that produces two different type of spores. Spores can be different in shape and size and that's the name heterosporous. It produces two different shaped spores to differentiate between male and female gametophytes

Answer:

What the scientist is doing incorrectly is working on a computer console with several monitors, having tubes and flasks of chemicals or biological substances on the same work table, many of which have fallen to the floor breaking and spilling their contents.

Explanation:

In the image it can see that a scientist works with a computer, placed in a long table where there are a lot of flasks and test tubes, many of which contain substances and have fallen to the ground, breaking and perhaps spilling their contents. This is a incorrect practice, as there should be a console for the computer, while the laboratory material should be on separate work tables.

Following these procedures is important to maintain biosafety standards and avoid accidents that affect the work in progress or the health of staff.

Explanation:

Its right I just took a test on it.

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. 

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

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.

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.

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.

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.

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.

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.

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.

Answer: The nucleus controls and regulates the activities of the cell and carries the genes, structures that contain the hereditary information.

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.

Answer and Explanation:

a. According to Lamarck, the origin of the long hind legs of the Ord's kangaroo rat is acquired due to extensive use of the muscle legs to jump. Such physical characteristics could be transmitted to future generations. This theory is called Neo-Lamarckism.

b. Darwin, on the other hand, theorized that in a population of Ord's kangaroo rat, there was an individual whose characteristics, long tail and hind legs, had more chances of escaping its predator and, consequently, could survive and reproduce. This theory is called Darwinism.

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.
