Answer: Nitrogen-fixing Bacteria

Explanation:

In the Nitrogen cycle, nitrogen fixing bacteria are very important in ensuring that plants get nitrogen to enable them grow and as animals have to eat plants, these bacteria are essential for our survival as well.

Plants are unable to use atmospheric nitrogen but nitrogen-fixing bacteria are able to synthesize ammonia from atmospheric nitrogen. They can then convert this to Nitrites and Nitrates which are more useful to plants and animals by extension.

stuaries are areas of water and shoreline where rivers meet the ocean or another large body of water, such as one of the Great Lakes. Organisms that live in estuaries must be adapted to these dynamic environments, where there are variations in water chemistry including salinity, as well as physical changes like the rise and fall of tides. Despite these challenges, estuaries are also very productive ecosystems. They receive nutrients from both bodies of water and can support a variety of life. Because of their access to food, water, and shipping routes, people often live near estuaries and can impact the health of the ecosystem.

shallow water, reef-building corals have a symbiotic relationship with photosynthetic algae called zooxanthellae, which live in their tissues. The coral provides a protected environment and the compounds zooxanthellae need for photosynthesis. In return, the algae produce carbohydrates that the coral uses for food, as well as oxygen. The algae also help the coral remove waste. Since both partners benefit from association, this type of symbiosis is called mutualism.

Deep-sea corals live in much deeper or colder oceanic waters and lack zooxanthellae. Unlike their shallow water relatives, which rely heavily on photosynthesis to produce food, deep sea corals take in plankton and organic matter for much of their energy needs.

Answer:

less packaging of oxygen

Explanation:

normal RBC (red blood cells) have a large surface area for oxygen packaging due to its biconcave shape but when mutation occurs the RBC being produced by the short bones is sickle shaped reducing surface area of haemoglobin exposed, responsible for packaging oxygen so tissues don't get right amount of oxygen

Answer: The common botanical name for beans is Phaseolus vulgaris.

Answer:

Vhaseolus Vulgaris

Explanation:

The botanical name of bean is Phaseolus Vulgaris

Answer:

True

Explanation:

An allele refer to two alternative forms of the same gene. An allele is a pair of genes found on a given chromosome. Usually, every allelic pair has one which is dominant and one which is recessive.

The dominant allele is expressed while the recessive allele is not expressed.

The colour of the pea plant is controlled by a pair of alleles wherein purple (P) is dominant to white (p).

The expressed colour of the pea plant(phenotype) is dependent on the arrangement of the genes(genotype) of the pea plant.

Answer:

The correct answer is - 15.13%

Explanation:

According to the question, the exposure of the pesticide X to the skin of John is by different routes and amount of the exposure is given and the percentage value is calculated as well:

Route of exposure --- exposure in gram---Dose in gram

Dermal ------------------------32-----------------------32*5/100= 1.6

Oral------------------------------2-----------------------2*90/100= 1.8

Inhalation----------------------5-----------------------5*50/100= 2.5

Total --- -----------------------39 -----------------------5.9

On the basis of this, the exposure is mainly by inhalation, the total exposure is about 39 grams about 5.9 percent. However,

The percentage of dose exposure = (5.9/39)*100

= 15.13%

Answer:

1. Leads to mixing of genetic materials hence variation within species

2. Leads to offspring with hybrid viguor that tend to show high and adaptability to environmental conditions.

3. Variations due to sexual reproduction leads to improvement of species hence evolutionary changes that may bring about specialisation

Answer:

The functional group highlighted in pink alternates its position on the carbohydrate molecule

Explanation:

Complex carbohydrates or polysaccharides are large molecular weight molecules composed of repeating unit of simple carbohydrates which are joined together by covalent bonds known as glycosidic bonds. These glycosidic bonds are foremd between the carbon at position number 1 (known as the anomeric carbon) of one simple carbohydrate and a hydroxyl group of another simple carbohydrate.

The configuration of these linkages determines the properties and functions of the complex carbohydrates. The complex polysaccharides starch, glycogen and cellulose are all composed of glucose monomers linked together by glycosidic bonds.

In storage polysaccharides such as starch and glycogen whose function is to store the simple carbohydrate glucose for when needed by the organism, the glycosidic linkages are said to be in α-linkages, placing the functional groups (CH₂OH) all on the same side.

Even the branching points in glycogen are all in α-linkages. Humans have the enzymes to break these bonds so that starch and glycogen molecules can be metabolized by the body.

In a structural polysaccharide such as cellulose, the glycosidic linkages are β-linkages which results in alternating positions for the functional groups. Since humans do not have the enzymes responsible for the breakage of these linkages, hence, we cannot digest cellulose in our bodies.

Answer: Cellular respiration is the process by which cells in plants and animals break down sugar and turn it into energy, which is then used to perform work at the cellular level.

Answer:

3.94 atm

Explanation:

Using the general gas law equation as follows;

PV = nRT

Where;

P = pressure (atm)

V = volume (L)

n = number of moles (mol)

R = gas law constant (0.0821 Latm/molK)

T = temperature (K)

According to the information provided in this question;

P = ?

V = 50 L

T = 300K

n = 8 mol

Using PV = nRT

P = nRT/V

P = (8 × 0.0821 × 300) ÷ 50

P = 197.04 ÷ 50

P = 3.94 atm

Answer:

The correct answer is - D. All of these are correct.

Explanation:

It is clear that the terrarium is sealed or not, if it is open to the outside environment or not. Considering it sealed and no outer interaction, then if a fake plant to this terrarium then there will be no photosynthesis will take place as there are no green plants to capture the sunlight and make glucose and no way to release oxygen for the other organisms.

If in this no green plants then the removal of CO2 will not be possible. Higher amount of carbon and without oxygen turtles would not be able to survive even though there is food for them.

Answer and Explanation:

a. This is a complete flower. Complete flowers are those formed by chalice, corolla, androecium and gynoecium. In the case of the flower presented above, we can see that it has gynoecium because it has a stigma that is part of the gynoecium composition. We can also see that she has androecium, because she has an anther that is part of the composition of androecium. The flower also has a corolla and chalice, since the chalice is formed by the sepals and the corolla by the petals.

b. This is a perfect flower, as we can see that androecium and gynoecium are present in the same flower. Imperfect flowers are those with only androecium or gynoecium.

c. The flower has bilateral symmetry, which is common in all orchids. This type of symmetry allows the flower to only be divided into two equal parts. Radial symmetry, on the other hand, allows flowers to be divided into many equal parts.

Answer:

Zebra mussels negatively impact ecosystems in many ways. They filter out algae that native species need for food and they attach to--and incapacitate--native mussels. Power plants must also spend millions of dollars removing zebra mussels from clogged water intakes.

Answer:

La biomasa (energía) se refiere a la biomasa «útil» en términos energéticos formales: las plantas transforman la energía radiante del Sol en energía química a través de la fotosíntesis, y parte de esa energía química queda almacenada en forma de materia orgánica; la energía química de la biomasa puede recuperarse quemándola directamente o transformándola en combustible.

Explanation:

Answer:

A. Destruction of terrestrial biota

Explanation:

all the other answers would decrease the carbon output. thickening of ocean sediments reinforces a carbon reservoir (which stores carbon), reduction in the use of fossil fuels would reduce the amount of carbon emissions, increase in marine biota = increase in carbon storage because marine biota is also a carbon reservoir.

Destruction of terrestrial biota would cause excess output because terrestrial biota is a carbon reservoir, and all of that carbon would be released into the carbon cycle.

Answer:

D the upper layers

Explanation:

at first, lifeforms were simple. they got more complex for a variety of reasons, including to adapt to the changing earth. simple organisms will be lower down for that reason.

The lower layers should contain fossils of more complex organisms. So, the correct option is (C).

A fossil is defined as the preserved remains, imprint or trace of something that once lived from a previous geological era. Examples of fossils are bones, shells, exoskeletons, fossilized traces of animals or microbes, objects preserved in amber, hair, petrified wood, and DNA residues. The totality of fossils is known as the fossil record.

There are four main types of fossils which are formed in different way  are conducive to preserving different types of organisms. Fossils are mold fossils, cast fossils, trace fossils and true form fossils.

Fossil layers are fossils that formed in sedimentary rock that formed in layers by depositing and pressing sediments on top of each other.

Thus, the lower layers should contain fossils of more complex organisms. So, the correct option is (C).
