Answer: D. redwood tree forests

Redwood forests can be significant reservoir for fixing atmospheric carbon dioxide. Through photosynthesis the redwood tree captures the atmospheric carbon and convert it into glucose as an energy reservoir for trees. Also, the soil organic matter of redwood forests is the accumulation of dead plant material, partially decayed or completely decayed plant and animal matter fixes carbon in the form of decomposed matter. This decomposed matter is again absorbed by plants. Hence, maintains the balance of carbon in the ecosystem.

The correct answer is: [D]:

___________________________________________________

→ " redwood tree forests " .

___________________________________________________

Note: Let us consider the other answer choices.

___________________________________________________

Choice: [A]: "garden flowering plants" ; is incorrect — since these are not generally considered to be part of a true or traditional "ecosystem" ; and especially since "garden flowering plants" are, in fact, "flowering plants" — which means that they are "angiosperms" — Not "gymnosperms ".

→ Rule out: " Choice: [A] " .

__________________________________________________

Choice: [B]: " ferns and liverworts " ; is incorrect — since both ferns — as well as liverworts — are Not "gymnosperms ".

Liverworts are "bryophytes" {which lack true vascular tissue] ; and ferns are "pterophytes" ["seedless vascular plants"].

→ Rule out: " Choice: [B] " .

___________________________________________________

Choice: [C]: " mosses and horsetails "; is incorrect ; since both mosses — as well as horsetails — are Not "gymnosperms ". Mosses are "bryophytes" (see aforementioned) ; and horsetails are "non-seed bearing plants" that spread vegetatively [underground; by asexual reproduction — and Not by seed .].

→ Rule out: " Choice: [C] " .

__________________________________________________

Choice: [D]: " redwood tree forests " ;

— is the only answer choice provided that is a "gymnosperm".

Furthermore, the "redwood tree" is a conifer (i.e. "coniferous; or, "cone-bearing" plant} that reproduces through seeds spread by "cone") — and all "conifers" are a type of "gymnosperm."

Furthermore, "redwood trees" grow large and tall, and redwood forest communities within an ecosystem; due to there size and presence, are: "known to be important in maintaining the balance of carbon in an ecosystem."

__________________________________________________

→ As such, the correct answer is:

__________________________________________________

→ Answer choice: [D]: " redwood tree forests " .

What are some possible risks factors associated with biological measurements due to poor classification/s

Mrac [35]

Biological measurements are the parameters associated with biological systems. An incorrect diagnosis and medical interventions are some measurements due to poor classification.

<h3>What are risk factors?</h3>

Risk factors are the biological, psychological, or social influences that affect the result or the outcome that can be positive or negative. The biological measurement risk factors might include the organism's system.

The poor classification of the biological risk factor can lead to an incorrect diagnosis of the condition followed by medical treatment and procedures that might have side effects.

Therefore, the medical diagnosis and intervention can be some risk factors.

Answer:

So that in a guinea pig cross in the offspring the recessive trait —long hair— can be observed in 25%, the most probable genotype of the parents is heterozygous Ss.

Explanation:

In guinea pigs, for the characteristic hair length, short hair is the dominant allele and long hair is the recessive one.

In order for 25% of the offspring to express the recessive characteristic, the parents must have a recessive genotype, which can be seen in Punnett's Square:

P: Ss X Ss

Alleles S s

S SS Ss

s Ss ss

Where the offspring is:

50% Ss with short hair phenotype
25% SS with short hair phenotype
25% ss whose phenotype would be long hair.

According to this, heterozygous parents for the characteristic long hair in guinea pigs have a 25% chance of having offspring with long hair.

For the History of Classification Quick Check(2021-2022):

Sholpan [36]

In this question we will do a Biological Classification History Check.

<h3>1. Binomial nomenclature</h3>

Binomial nomenclature or binary nomenclature designates the set of rules that regulate the attribution of scientific names to species of living beings.

<h3>2. Domain</h3>

Is based on molecular phylogeny data. According to Woese, there are three domains: Archaea Domain, Bacteria Domain, and Eukarya Domain.

<h3>3. Both focus on illustrating taxonomic relationships between organisms.</h3>

No, binomial nomenclature is for the purpose of assigning names.

<h3>4. domain, kingdom, phylum only.</h3>

No, the classification is more extensive

<h3>5. juglans nigra</h3>

It is a tree that can reach heights between 20 to 50 m. It is still a monoecious, deciduous and aromatic tree.

You own a winery in Napa Valley. An assistant accidentally leaves the lid for a vat of wine slightly ajar. Would the yeast insid

anastassius [24]

When the lid for a vat of wine is slightly open, the yeast inside can continue to perform alcoholic fermentation because the carbon dioxide produced by the yeast during fermentation will act as a blanket over the wine. Nevertheless, the air around the fermenter must be still and enough carbon dioxide should be produced to continue alcoholic fermentation. However, at some point, carbon dioxide will fall and can no longer protect the wine. This is the right time to get your wine covered before it will be vulnerable to undesirable microorganisms.

Therefore, open fermentation is good in the early stages of fermentation because yeast need oxygen to synthesize sterols and assimilate fatty acids to ensure the nutrients it needs to multiply and ferment the 70% of the sugar from the fruit. Furthermore, the yeast is responsible in decomposing sugar from the grapes into alcohol and carbon dioxide.
