You observed many sand hill cranes on your walk. Two sand hill cranes flapped their wings and hopped up and down when you walked

Anarel [89]

Answer:

This question lacks options, the options are:

A) symbiosis

B) ecosystem

C) community

D) population

E) biosphere

The answer is D) Population

Explanation:

Living organisms in an ecosystem are usually found in numbers living together in a given area. This is termed POPULATION in ecology. A population refers to the group of living organisms that belongs to the same species living together in the same habitat and have the ability to interbreed i.e. mate and reproduce with one another.

This is the case in this question where many sandhill cranes (large flying birds) were observed in a particular area, which represented their habitat. Asides the group of sandhill cranes living together, they were also observed to be interbreeding. This was evident in the observation of two sandhill cranes hopping up and down around their bright orange baby. This shows that members of the population are capable of mating and reproducing fertile offsprings.

This observation completes what a POPULATION is all about, hence, a population was observed.

Living organisms make and use three main types of ribonucleic acids (RNA) for their biological functions: ribosomal RNA (rRNA) m

serg [7]

Answer:

<u>Part A</u>

Drag these words to the space

(1) tRNA: "contains an anticodon" "has amino acids covalently attached in active form"

(2) mRNA: "has introns and exons" "contains genes for a protein"

(3) rRNA: "is found in ribosomes" "is the most abundant form of RNA"

<u>Part B</u>

(1) Replication: Leave blank because no RNA is involved .

(2) Transcription/RNA processing: mRNA because it is synthesized from the information in DNA

(3) Translation: rRNA and tRNA

explains respiration including the reactants and the products, its purpose and the organelle it occurs in.

ziro4ka [17]

Respiration is the transformation of glucose to ATP, which is energy that the body can use.
Respiration consists of several steps: glycolysis, TCA/Krebs/Citric acid sycle and at last the oxidative phosphorylation.
The molecules needed for this to happen is water, oxygen (O2), NADH, ATP and glucose.

Based on the information below, answer the following three questions, assuming complete dominance.

scoray [572]

Answer:

100%

Explanation:

Let’s represent the dominant tongue rolling trait as: R

and the recessive trait as: r

A homozygous individual will have the same alleles i.e. RR (for dominant), rr (for recessive). Note that Rr is heterozygous.

An individual homozygous dominant for tongue rolling has the alleles RR

and an individual who cannot roll his tongue has rr, that is homozygous recessive .

To determine the trait of their offspring, we'll cross their traits

Crossing the two :

RR x rr

Rr, Rr, Rr, Rr

All the offspring will inherit the dominant R and the recessive r from both parents.

Therefore, there is a 100% chance that the child will have a heterozygous genotype.
