Why is it that although Nocardia spp. grow well on most common nonselective laboratory media, many are missed when the cultures are read

Answers

Answer 1

Answer:

These organisms require 3 to 6 days to grow.

Explanation:

Nocardia are a group of actinomycetes. Some of the species of the nocardia are pathogenic to the humans. There are more than 70 species of nocardia in the world.

Some of the Nocardia spp. grow on the most common non laboratory media but many of them are missed out when the cultures are read because these organisms requires at least 3 days to 6 days to grow.

How does reproductive isolation cause speciation?
A. It flows interbreeding.
B. It stops adaptive radiation.
C. It reduces gene flow.
D. It prevents divergence.

Answers

Answer:

C. It’s reduces gene flow.

Explanation:

Reproductive isolation cause speciation as it reduces gene flow. Therefore, the correct option is C.

Mechanisms that prevent or restrict the exchange of genetic material (gene flow) between populations are called reproductive isolation. When reproductive isolation occurs, populations become genetically isolated from each other, resulting in different evolutionary paths. This may eventually lead to the speciation or evolution of new species. Reproductive isolation limits the exchange of genetic variation between populations by limiting gene flow. This means that genetic changes, such as mutations or genetic drift, that occur in one population do not affect other populations in the same way.

Therefore, the correct option is C.

An element symbol begins with a capital letter; if there is a second or even third letter, it is a lowercase letter.

Answers

Answer:

- An element is a pure substance that cannot be broken down into a simpler form.

- All elements are listed on the periodic table of elements.

- An element symbol begins with a capital letter; if there is a second or even third letter, it is a lowercase letter

Explanation:

An element is one of the two types of pure substances i.e. substances that cannot be broken down into simpler forms. Elements are made up of only one type of atom e.g. Fe, Cl2 (two chlorine atoms).

All known or discovered chemical elements are represented on the periodic table. In an order of increasing atomic number, elements are arranged from left to right on the periodic table.

The symbol of an element begins with a first letter written in capital letters while the subsequent letters can be written in lower cases. For example, Fe, Cu, Hg, Zn etc.

observe the given relation and fill in the blanks cucumber: tendril citrus: meiosis: reduction division mitosis:​

Answers

Answer:

citrus: thorns

mitosis: equational division

Explanation:

From the relationship:

Tendrils are thread-like appendages found in most climbing plants. They primarily function as supporting organs for climbing plants (such as cucumber) by stretching out and twinning around physical supports. The equivalence of this in citrus is the thorn.

Meiosis is a reductional cell division in which the chromosome number of the daughter cells is half of that of the other cells. Mitosis is equational division because the chromosome number of the parent cell is the same as that of daughter cells.

In the electron transport chain, which structure forms a channel in the inner membrane of the mitochondria and adds phosphate to ADP

Answers

Answer: ATP synthase

Explanation:

The ATP synthase complex is an enzyme located in the inner membrane of the mitochondrion that catalyzes the synthesis of ATP from ADP, a phosphate group and energy supplied by a proton (H+) flux. This ATP synthesis occurs during cellular respiration, which is a set of biochemical reactions by which certain organic compounds are completely degraded by oxidation to inorganic substances. This process provides usable energy to the cell in the form of ATP.

During cellular respiration, ATP synthesis is termed oxidative phosphorylation and the proton flux takes place between the intermembrane space and the mitochondrial matrix. ATP synthase produces ATP when protons flow through it. The proton flow creates a pH gradient and an electrochemical gradient. This proton gradient is used by ATP synthase to form ATP via oxidative phosphorylation. ATP synthase acts as an ion channel that "returns" protons to the mitochondrial matrix. During this return, the Gibbs free energy produced during the generation of the oxidized forms of electron transporters is released. This energy is utilized for ATP synthesis. It must then be considered that the electron transport chain and oxidative phosphorylation are coupled by the proton gradient.

Georges Cuvier.

Explanation:

Georges Cuvier (1769-1832) fue un zoólogo quien propuso que la evolución era el resultado de extinciones producidas por catástrofes a las cuales les sucedían nuevas creaciones con distintas especies. Los ecosistemas con las catástrofes eran destrozados y en los suelos de estos quedaban los  restos de los animales extintos formando parte de los estratos de la tierra.

Some protozoans have special organelles called contractile vacuoles that continually eliminate excess water from the cell. The presence of these organelles tells you that the environment Group of answer choices is hypotonic to the protozoan. contains a higher concentration of solutes than the protozoan. is isotonic to the protozoan. is hypertonic to the protozoan.

Answers

Answer:

is hypertonic to the protozoan.

Explanation:

The presence of contractile vacuoles tells us that the environment  is hypertonic to the protozoan that contains a higher concentration of solutes in the outside environment than the protozoan. The water moves outside the cell if its concentration is higher inside the cell so due to diffusion and no need of extra water, the water removes by the contractile vacuole to the outside environment so we can say that the environment is is hypertonic to the protozoan.

Answer:

Meiosis II is very similar to mitosis; chromatids are separated into separate nuclei. As in mitosis, it is spindle fibers that “pull” the chromosomes and chromatids apart. The end result of meiosis is four cells, each with one complete set of chromosomes instead of two sets of chromosomes.

After ATP donates a phosphate group to a coupled reaction, then it becomes ADP. The ADP Group of answer choices can be recharged in an equilibrium reaction to form ATP. can be recharged in an oxidation reaction to form ATP. can be recharged with the release of energy to form ATP. is a waste product that will be broken down. can be recharged with the uptake of energy to form ATP.

Answers

Answer:

can be recharged with the uptake of energy to form ATP

Explanation:

The correct answer would be that the ADP can be recharged with the uptake of energy to form ATP.

ADP is converted to ATP within a cell when free energy is available. The free energy is stored by coupling a phosphate group to ADP to form ATP, such that:

ADP + P (inorganic) + Free Energy ------> ATP

Hence, ADP can only be recharged with the uptake of energy to form ATP, a kind of reaction generally referred to as endergonic reaction.
