Answer: False.

Explanation:

Thermodynamics describes the states of thermodynamic equilibrium at the macroscopic level. The states of equilibrium are studied and defined by means of extensive magnitudes such as internal energy, entropy, volume or molar composition of the system, or by means of non-extensive magnitudes derived from the previous ones such as temperature, pressure and chemical potential.

Thermodynamics deals with the processes of heat transfer, which is one of the forms of energy and how one can work with it. This area describes how matter in any of its phases (solid, liquid, gas) is transformed. So from a macroscopic point of view of matter, it studies how it reacts to changes in its volume, pressure and temperature, among other magnitudes. Thermodynamics is based on four main laws:

Thermodynamic equilibrium (or zero law)
The principle of conservation of energy (first law)
The temporary increase of entropy (second law)
The impossibility of absolute zero (third law).

In thermodynamics, a system is said to be in a state of thermodynamic equilibrium if it is incapable of spontaneously experiencing any change of state or thermodynamic process when it is subjected to certain boundary conditions (the conditions imposed by its surroundings). For this purpose, it must be simultaneously in thermal equilibrium, mechanical equilibrium and chemical equilibrium.

Entropy (symbolized as S) is a physical magnitude for a thermodynamic system in equilibrium. It measures the number of micro states compatible with the macro state of equilibrium, it can also be said that it measures the degree of organization of the system, or that it is the reason for an increase in internal energy versus an increase in temperature of the thermodynamic system.

Entropy, in an isolated system, grows in the course of a naturally occurring process. A consequence of the second law of thermodynamics is that in a state of equilibrium, entropy has a maximum value in the system that will correspond to a minimum in one of the thermodynamic potentials.

In a group of muskmelon plants, some individuals have sour fruit and others have sweet fruit. in this group, the gene for the fr

juin [17]

Correct option(s):

(b) This muskmelon plant's genotype for the fruit taste gene is ff.

A dominant allele is one that is capable of expressing itself even in the heterozygous condition and overshadows the effect of the recessive allele. It is usually denoted by a capital letter. Recessive allele on the contrary cannot express in presence of a dominant allele and is denoted by a small letter.

In the given case the fruit with a sour taste (phenotype) can have two possible genotypes (FF and Ff). The genotype of sweet taste is ff which is a homozygous condition.

Note: Your question is incomplete, probably your complete question is “In a group of muskmelon plants, some individuals have sour fruit and others have sweet fruit. in this group, the gene for the fruit taste trait has two alleles. the allele F is for sour fruit, and the allele f is for sweet fruit. a certain muskmelon plant from this group has sweet fruit. this plant has two alleles for sweet fruit. Choose the correct option:

(a) this muskmelon plant's genotype for the fruit taste trait is sweet fruit.

(b) this muskmelon plant's genotype for the fruit taste gene is ff.

Which best blocks X-ray particles and can therefore be observed more closely through the use of this technology?

Vedmedyk [2.9K]

Answer:

The correct answer would be bones.

X-rays are high energy electromagnetic waves which have an ability to penetrate most of the biological tissues.

In the X-ray machine, a beam of high energy X-rays is passed through the filters and subject and then fall on the detector or photographic film to produce X-ray.

Dense tissues like bone, teeth, tumors et cetera blocks or stops most of the X-ray particles from reaching the detector or photographic film.

It forms glowing pictures on the X-ray film or photographic film.

The denser the material the brighter the image will be formed on the photographic film.

Select all that apply The cellular respiration the mitochondrion serves as?

SVEN [57.7K]

D. The Krebs cycle

Here’s the Explanation for it:

The Cellular respiration refers to the biochemical pathway in which the cells release energy from chemical bonds of food molecules. The energy that is provided is very important to the creation of life itself.

The aerobic phases of the cellular respiration in eukaryote is seen within mitochondria (organelles). This is know as the Krebs Cycle and the electron transport chain which are aerobic phases.

Hope this helps!
