Is human blood ever any color other than red?
Answers
Answer:
no
Explanation:
Human blood is red because of the protein hemoglobin. Hemoglobin contains a red-coloured compound called heme that’s important for carrying oxygen through your bloodstream
Sometimes blood can look blue through our skin, but its never blue. the reason we see blue is because blue light doesn't go as deep into kin as red. If the blood vessel is deep, your eyes see more blue than red light due to the blood’s absorption of red wavelengths.

RNA interference (RNAI) is a mechanism of gene regulation in eukaryotes. RNAI is initiated by ____, which leads to the ____ of specific genes.
Box 1:
single-stranded RNA
double-stranded RNA
double-stranded DNA
Box 2:
silencing
induction
expression
Answers
Answer:
double-stranded RNA; silencing
Explanation:
The RNAi mechanism is a natural process of gene silencing triggered by different small non-coding RNAs such as, for example, siRNAs, miRNAs and piRNAs. RNAi is a powerful technique to induce gene silencing in a sequence-specific manner. The delivery of exogenous double-stranded RNAs (dsRNAs) can be used to induce this evolutionarily conserved mechanism. The dsRNAs first bind to RNAi core components (Ago, Piwi proteins) and then target complementary mRNAs to induce their degradation.

Explanation:
The codon is the three nucleotide sequence in the mRNA that indicates which amino acid should be incorporated in the growing polypeptide chain.
What is Codons?
The anticodon is the complementary three nucleotide sequence in the appropriate tRNA. Template stand is the DNA strand off which the mRNA is synthesized.
Codons are units of genomic information made up of three nucleotides (trinucleotides) in DNA or RNA that code for a specific amino acid or indicate the end of protein synthesis (stop signals). There are 64 distinct codons, of which 3 serve as stop signals and 61 identify amino acids.
The bases that make up DNA and the associated messenger RNA are called bases. These nucleotides are frequently identified in RNA by the letters A, U, C, and G.
Therefore, The codon is the three nucleotide sequence in the mRNA that indicates which amino acid should be incorporated in the growing polypeptide chain.

Please help me in my homework (keep it simple,i couldnt find Science ;-; I am sorry) What is environment? What are three main aspect of environment? 2)Write down any four importance of environment.
Answers
Answer: It is then the space in which the life of living beings and the interaction between them and other things takes place. It is made up of living organisms, abiotic elements and artificial elements. It includes physical, chemical and biological components of the organisms and elements that form it. It is important because it is the place of habitat of humanity, it provides natural elements such as water and food, it provides fuels and raw materials that serve to manufacture artificial things and it contributes to the sustainability of life on the planet.
Explanation:
The environment is a system made up of living organisms (such as animal and plants), abiotic elements (lifeless, such as stones or water) and artificial elements (created by man, such as buildings) that are related to each other and can be modified by human action. It is then the space in which the life of living beings and the interaction between them takes place.
It includes physical, chemical and biological components of the organisms and elements that form it. That is, how is its composition and its function in the environment.
The importance of the environment lies in:
It is the place of habitat of humanity, so it influences the life of human beings and future generations. It is the space where life develops at this time with all living beings and their natural components.It provides natural elements such as water and food since it offers all its natural resources needed by the human being. It provides fuels and raw materials that serve to manufacture the artificial things we use daily, to build houses, have light, transport, among many other benefits to exist. In the environment we find a great biological diversity of plants and animals that help maintain the ecological balance of the earth. This contributes directly to the sustainability of life on the planet. Each organism has a unique role to play.Therefore, all societies must guarantee their care for their existence and make rational use of all their resources.

In guinea pigs the allele for black fur (B) is dominant over the allele for brown fur (b), and the allele for short fur (F) is dominant over the allele for long fur (f). What percentage of the offspring from a BBFF x bbff cross would be expected to be heterozygous for both traits?
Answers
Answer:
100%
Explanation:
This question involves two genes in guinea pigs; one coding for fur color and the other for fur length. The alleles of black fur (B) and short fur (F) is dominant over the alleles for brown fur (b) and long fur (f).
In a cross between two offsprings with genotypes: BBFF x bbff, the following gametes will be produced by each parent:
BBFF - BF, BF, BF, and BF
bbff - bf, bf, bf, bf
Using these gametes in a punnet square (see attached image), one will notice that all of the offsprings will have the genotype: BbFf i.e all or 100% of the offsprings are heterozygous for both of the genes or traits.

Once pollen lands on the stigma, it forms a pollen ____________________ down through the long_____of the pistil [the female reproductive part] into the flower's ______– which contains ovules. fill in the blank
Answers
Answer:
1. Pollen tube
2. Style
3. Ovary
Explanation:
This process is describing the process of POLLINATION, which is the transfer of pollen grains from the anther of a male flower (androecium) to the stigma of the female flower (gymnoecium). After pollination i.e. the pollen has landed on the sticky stigma, the pollen grows out a tube called POLLEN TUBE.
The pollen tube extends through the STYLE of the female flower called PISTIL to the OVARY. The ovary is the reproductive part of the female flower that produces the ovules, which the sperm in the pollen is about to fertilize.

Answer:
A two-word name for organisms where the word is the genus and the second word is the species
Explanation:
Binomial nomenclature is the system biologists use to name species of living beings. When we translate this term, we get the two-name naming system. This tells us a lot about how species are named - their name consists of two components. The first component is the name of the genus the species belongs to and the second is the name of the species. For example, the scientific name used for cats is Felis catus. Felis is the genus and the species is catus.
