Which tool is used to test for nitrates?

A. turbidity test
B. pH meter
C. soil testing kit
D.water quality testing kit

Answers

Answer 1

The tool which is typically used for testing nitrates is: C. soil testing kit

Nitrogen is a chemical element with the symbol "N" and it has an atomic number (number of protons) of 7.

Basically, nitrogen is found in group (5) of the periodic table and as such it has 5 electrons in its outermost shell.

Oxygen is a chemical element with the symbol "O" and it has an atomic number (number of protons) of 8.

Generally, when nitrogen and oxygen react chemically, they produce a compound known as nitrogen dioxide.

In Chemistry, nitrates are chemical compound that comprises nitrogen and oxygen.

Also, nitrates are used in the production of soil fertilizers in agriculture.

In conclusion, a soil testing kit is mainly used to test the presence of nutrients such as nitrates in soils.

The vertebrate lung first appeared in ___________.

Answers

Answer:

fishes

Explanation:

A progenitor feature found in early boney fish served as the basis for the development of the vertebrate lung.

What are vertebrate lungs?

The lung of modern vertebrates evolved from a structure that was present in the ancestors of early boney fish.

Lungs in vertebrates originated as extra air-breathing organs in primordial fishes and were ventilated by buccal pumping when they first appeared. In more modern fishes, the organ formerly known as the lungs has been replaced with the hydrostatic swimbladder. This fundamental kind of unicameral lungs and the buccal pumping ventilation observed in these lungs can also be found in more modern amphibians.

If you are experiencing Na channels deactivating the plasma membrane which hyperpolarizes the membrane which sense is being activated?

Answers

The options are missing from the question,below are the options.

A) touch

B) smell

C) hearing

D) sight

The correct answer to the question is option D

SIGHT.

If one is experiencing Na channels deactivating the plasma membrane,the sense that is being activated is SIGHT,

this is because in the red blood cell,the light induced isomerization of the moiety retinal rhodoesin produce activated opsin which goes ahead to activate the signal transducing G-protein transducin,this it does by catalyzing exchange of GTP (Guanosine triphosphate) for bound GDP(guanosine diphosphate) on the subunit.

This GTP in turn activates the level of CGMP (Cyclic guanosine monophosphate) phosphodiesterase and it further acts to lower the level of CGMP.

Upon this reduction,it leads to the closing of CGMP-gated Na+ channels and hyperpolarization of the membrane.

An organism has a diploid number of 32. What would be the number of chromosomes found in the
cells of this organism undergoing mitosis? Explain.

Answers

Answer:

There is no gamete formation meiosis in these organisms. A diploid zygote ( 2n = 32) will undergo replication to produce 4n = 64 chromosomes.

Explanation:

The number of chromosomes found in the cells of this organism undergoing mitosis would be 32.

What is Mitosis?

Mitosis may be defined as a type of cell division that two genetically identical daughter cells from a single parental cell. In this type of cell division, each daughter cell has the same number and kind of chromosomes as compared to the parent nucleus.

During mitosis, a diploid cell produces two genetically identical daughter cells with the same number of chromosomes. Hence, in this question, an organism contains a cell of diploid nature with a number of chromosomes equal to 32.

As a result of this, the number of chromosomes found in the cells of this organism undergoing mitosis will remain the same and that is 32.

Therefore, the number of chromosomes found in the cells of this organism undergoing mitosis would be 32.

1. What is an example of an illness that requires airborne precautions?

Answers

Answer:

measles

Explanation:

Shifting biomes could have consequences for the regions in which the shifts occur. Read the two cases below and decide which consequences would apply to one or both cases.Case 1: The biome of a small agricultural community in the western United States changes from grassland to desert. A species of migrating duck, which can carry bird flu, goes locally extinct.Case 2: The biome in northern Russia changes from tundra to taiga. Timber harvesting in the region becomes possible. Arctic foxes go locally extinct and are replaced by red foxes that commonly carry rabies.Sort each consequence based on whether it would apply to Case 1, Case 2, or botha. increased risk of wildfiresb. local economy suffersc. carbon storage decreasesd. agricultural production decreasese. carbon storage increasesf. disease vector range changesg. decreased water availabilityh. local economy thrivesi. species range changesCase 1Case 2Cases 1 and 2

Answers

Answer:

increased risk of wildfires- both

local economy suffers- Case 1

carbon storage decreases - Case 2

agricultural production decreases - Case 1

carbon storage increases -  Case 1

disease vector range changes - Case 2

decreased water availability - Case 1

local economy thrives - Case 2

species range changes - Case 2

Explanation:

Fires are common to  taiga biomes. Owing to the fact that the biome in case 1 changed from an agricultural community to a grassland and subsequently to a desert, agricultural productivity will decrease, the local economy will suffer, water availability is decreased and local economy suffers as a consequence of desertification.

On the other hand, in case 2, the diseases vector range as well as species range changes due to the change in the species of foxes from Artic foxes to red foxes that carry rabies. Carbon storage decreases as the taiga biome acts as a carbon sink. The local economy thrives due to timber production.

Lastly, species range changes both in case 1 and case 2 since there is a loss of species. Species range is the area where a particular species can be found during its lifetime. Certainly, the range of area where species are found changed in cases 1 and 2.

The consequences from the given cases are sorted as:

case 1: b. the local economy, c. carbon storage decreases, d. agricultural production decreases, f. disease vector range changes, i. species range changes, g. decreased water availability

Case 2: a. increased risk of wildfires, e. carbon storage increases, f. disease vector range changes, i. species range changes, h. the local economy thrives

Case 1 and 2 both: f. disease vector range changes, i. species range changes.

Consequences by shifting biomes?

Case 1:

The shifting of biome from the agricultural community in the United States changes from grassland to desert result in consequences like decrease in the carbon storage and local economy suffers because of reduction in the agricultural production.

Also since the biome changes to the desert, it results in decreased water availability. Also since the biome changes, a species of migrating duck that carries flu goes locally extinct which implies that there will be a change in the range of species as well as the disease vector changes.

Case 2:

Since the biome in Russia changes from Tundra to Taiga now harvesting becomes possible and due to which carbon storage increases which in turn results in the flourishing of the local economy.

As an increase in the forests, there will be an increased risk of wildfires. Since the c foxes go locally extinct and are replaced by red foxes which carry rabies which implies that species range changes and the disease vector range changes.
