Answer:

Under law? Depending where and what biz is there is NO obligation, or little if any in most cases.

Under morals, aka higher principles most bussinesses would just have to close.

Under Biblical principles, to subdue is one thing, to destroy is another. Much can be done but won't be because of cost/politics over logic. Sometimes that too is a natural resource, it's called freedom and or liberty and someone is using a lever for an alternate motive just saying it's for the 'trees’. Other cases it's plain and clear destruction for profit and nothing is said.

Record forest fires have occurred in west, some of it because environmentalists interfered with forest management to the point of cost in court and in the field leaving nothing to do. Areas that needed undergrowth and deadwood removed were kept untouched decades. Red tape and global warming made fuel stack up.

Answer: 35 chromosomes

Explanation: somatic cells are diploid, gametes are haploid, so the gametes will have 35 chromosomes.

Answer:

Metabolic Engineering

Explanation:

Metabolic engineering refers to the process of modifying the genetic and enzymatic processes within cells in order to optimize the output of products. When constraints are noticed in the normal biological process, scientists endeavor to modify the constraints so that wide scale production can be realized.

Examples of processes that incorporate this technique are beer, cheese, wine and some drugs production.

Answer:

mimicry

Explanation:

Mimicry, in biology, phenomenon characterized by the superficial resemblance of two or more organisms that are not closely related taxonomically. This resemblance confers an advantage—such as protection from predation—upon one or both organisms by which the organisms deceive the animate agent of natural selection.

okay, the answer is D. mimicry. i mean- think about it: it cant be camouflage because like- camaflouge is where they hide like the stick bug. the stick bug camouflages into the tree. like- the stick bug has the same detail, looks like the tree. so it cant be camouflage. it cant be hibernation because snakes dont hibernate only fur animals do. snakes have scales. it cant be migration because only insects like butterflies, birds, and so on, only they migrate. snakes dont have wings. now we are left with D. if you think its A or D it can be but its D i got an A+ on my test with this question.

owls that prey on the mice

Explanation:

owls are the biotic or live factor that limits mice population because they hunt mice for food

Answer: b. A is acidic, B basic

Explanation: pH 7 is neutral, with equal H+ and OH-

pH is -log(H+ Molar Concentration) and at pH7, H+ and OH- are both at a concentration of 10^-7

A more acidic solution has more H+ than OH-, so it is a higher concentration than 10^-7 and therefore pH lower than 7. Conversely, a pH>7 means a higher concentration of OH- and lower concentration of H+

Considering the definition of pH, the correct statement is option b. A is acidic and B is basic.

You need to know that pH is the Hydrogen Potential. It is a measure of acidity or alkalinity that indicates the amount of hydrogen ions present in a solution or substance.

Mathematically, pH is calculated as the negative base 10 logarithm of the activity of hydrogen ions:

pH= - log [H⁺]

The scale has values ​​ranging from 0 to 14, with pH 7 being the neutral solution. Solutions with pH less than 7 are acidic and alkaline (basic) those with pH greater than 7.

Then, being the pH of solution A equal to 2, being less than 7, the solution is acidic. On the other hand, the pH of solution B is 8. As the pH is higher than 7, solution B will be basic.

So, finally, the correct statement is option b. A is acidic and B is basic.

Answer:

Punnett squares are used to show all of the combinations of alleles that might result from across and the likelihood that each might occur.

Explanation:

Punnett squares are diagrams used by biologists to determine the probability that offspring have a particular trait. The creation of Punnett Square and its use to determine the characteristics of offspring is called the performance of the cross.

The crosses in Punnett Square are based on meiosis, a biological process in which parents transmit alleles to gametes, which they later pass on to their offspring. Each parent has two alleles for the trait and passes one to their offspring. Each offspring completes a total of two alleles, one from each parent.

Answer:

Golgi complex

Explanation:

The Golgi complex, also known as the Golgi apparatus, is a cell organelle of eukaryotic cells that functions to sort different molecules which are destined to the plasma membrane. In the Golgi apparatus, proteins and lipids from the Endoplasmic Reticulum (ER) are subsequently processed and classified to be transported to different cell locations including, among others, the plasma membrane, or vesicles which are secreted from cells by exocytosis. Moreover, this organelle also contains specific enzymes (glycosylation enzymes) that function to modify proteins in order to form glycoproteins.

Answer:

The correct answer is -

1. Y (yellow) and y (green)

2. Yy (yellow dominant) and yy (green)

3. Two heterozygous yellow (Yy) and two green recessives (yy)

4. 50% Yellow and 50% green plant

Explanation:

In the given question, it is given that a pea plant has two alleles for the trait yellow seeds and green seeds, the alleles for the traits are green (y) and Y for the dominant trait.

The cross between the green seed (yy) pea plants, is recessive and heterozygous which means a combination of dominant and recessive are as follows:

    Y       y

y    Yy    yy

y   Yy   yy

Here two heterozygous yellow seeds and two recessive green seed plant offspring.

Answer:

oxygen bubbles

Explanation:

These bubbles are oxygen bubbles that are being produced by the aquatic plants at the bottom of the aquarium. As oxygen usually does it floats to the top of the water and back up into the atmosphere. This happens because of the photosynthesis process in which the plants soak up sunlight and carbon dioxide and uses it to produce and release oxygen. Since this process happens underwater for the aquatic plants the oxygen become bubbles and float up.

Size of particle.

Explanation:

Size of the particles that are diffusing is the factors that greatly affect the rate of diffusion. The rate of diffusion decreases if the thickness of the membrane becomes doubled while on the other hand, if the surface area of the membrane increases it doubled the rate of diffusion of the cell. If the size of particles is very small so it will diffuse if the membrane has double thickness.

Answer:

Metabolism is a set of chemical reactions that  they release energy for cellular processes.

Explanation:

Metabolic processes in cells are:

* Metabolism-the whole of all chemical processes, that is, the total turnover of matter and energy is called metabolism.

* Cellular respiration-a process in which organic matter is oxidized, whereby carbon dioxide, water, and energy in the form of ATP molecules are formed as end products of this oxidation.

Answer:

Enzymes promote chemical reactions by bringing substrates together in an optimal orientation, thus creating an ideal chemical environment for the reaction to occur. The enzyme will always return to its original state at the completion of the reaction.

Answer:

from water to land

Explanation:

during the day a land has higher temperature than water so the air is lighter on land and makes space for heavier one from water. that's why the air moves from water to land

the movement of air during the day from water to land

The physical property of Water are, it  is a colorless and tasteless liquid,  have extensive hydrogen bonds resulting in unusual properties in the condensed form.

This also have high melting and boiling points. As compared to other liquids, water has a higher specific heat, thermal conductivity, surface tension, dipole moment, etc.

Water is a great solvent and  helps in the transportation of ions and molecules required for metabolism, has high latent heat of vaporization helps in the regulation of body temperature.

It is Amphoteric nature can act as  both acid and base  means that it is amphoteric in nature, it is Electropositive elements which reduce water to hydrogen molecule and it is the source of hydrogen.

during the day a land has higher temperature  so the air is lighter on land and makes space for heavier one from water, hence the air moves from water to land
