How do flowering plants reproduce

Biology

There's 2 part in flowering plants reproduction.
pollination then fertilisation follows.
pollination is where pollen transfer from anther (male part) to stigma (female part) by wind or insect depending on the kind of flower.
once stigma received the pollen, it'll grow a pollen tube, in a sugary solution, then it travels through the style, and to the ovary by entering the micropyle (a small gap) when the nuclei of male and female gamete fused together , a zygote is formed and will be developed into a seed

What is the purpose of alternative splicing in eukaryotic cells? What is the purpose of alternative splicing in eukaryotic cells
Komok [63]

Answer:

Produce multiple polypeptide sequences from a single primary transcript.

Explanation:

Some genes produce more than one type of protein since the primary transcript encoded by these genes undergoes alternative splicing. These genes mostly have one segment that can serve either as intron or exon. Also called differential splicing, alternative splicing removes the segment as intron but retains it as an exon.

Splicing of the single primary transcript in different ways produces more than one version of mRNA from a single primary transcript encoded by a single gene. The alternative splicing allows the cells to produce multiple types of troponin proteins from single genes. These different troponin regulation muscle contraction in different muscles

A segment of a gene contains 27 nucleotides, none of which include stop or start codons. How many amino acids does this segment
blondinia [14]

If none of the nucleotides includes stop or start codons when a segment of a gene contains 27 nucleotides there will be 81 amino acids in this segment code.

Answer: Option B

<u>Explanation:</u>

Codon is a nucleotides within messenger RNA. A stop or start codon is a nucleotide triplet which signals protein termination. Start codons initiate to start translation while the stop codon initiates termination.

The genetic codes are the sequence for nucleotide that codes for amino acids. A segment containing 27 nucleotides multiplied by 3 gives 81 amino acids. Every nucleotide in an mRNA are read “three at a time”. Hence this segment codes for 81 amino acids.

In a species of ground finch that inhabits the Galápagos Islands, the average beak size increased over several generations from
victus00 [196]

Answer:

d. directional selection

Explanation:

Directional selection is a form of natural selection that occurs when a particular extreme phenotype of a species is highly favored and thrives more than the other extreme phenotype. This is particularly influenced by environmental changes resulting in differences in the survival between both extreme phenotypes.

In the Galapagos Islands during drought, the seeds to be fed on by finches are mostly large in size, giving rise to the survival of only finches with large beak size of 9 mm to 10 mm as against finches with small beak size. Finches with large beak sizes are favored over  finches with phenotypic traits of small beak sizes.

In some deserts, the air temperature can change over 60 to 70 degrees in a single day. Which of these properties
bazaltina [42]

Answer:

Being endothermic

Explanation:

Humans are not cold-blooded and we don't photosynthesise so only the second option applies to humans;

We produce heat internally within our bodies so we are endotherms, i.e. warm-blooded;

We shiver and have thermogenesis through metabolism to generate heat to keep body temp up and also sweating and physiological mechanisms to cool out bodies down.
