Answer: 30

Explanation:

Diploid is simply referred to as a cell or an organism which possess paired chromosomes. The paired chromosomes are gotten from each of the parents.

It should be noted that the total chromosomes that will be found in the cattle's somatic cell is 60. Therefore, the pair will be 60/2 = 30.

Answer:

a critical period

Explanation:

In developmental psychology and developmental biology, a critical period is a maturational stage in the lifespan of an organism during which the nervous system is especially sensitive to certain environmental stimuli(Wikipedia). It is a time during early postnatal life when the development and maturation of functional properties of the brain, its 'plasticity', is strongly dependent on experience or environmental influences(Sengpiel, 2007).

The fact that imprinting is most certain to occur if the opportunity for imprinting is presented to the organism at a very specific age indicates the existence of a critical period in the life of organisms.

Answer:

Dominant: the genes that are expressed/ shown

Recessive: the "hidden" genes

Explanation:

If one parent has a dominant gene for brown eyes and the other has a recessive gene for blue eyes, then the offspring will have brown eyes.

Hope this helps!

You can message me if you are still confused.

Explanation:

dominant genes will always appear before recessive ones, in order for recessive genes to appear, both copies of the gene have to be the recessive one tldr for this paragraph, think of dominant genes like jackets, and recessive ones like t shirts

an example

B=brown hair gene (dominant)

b=blond hair gene (recessive)

this is an example of 2 parents, with offspring

Bb Bb <-- both parents have a copy of brown and blond hair gene, but since dominant genes appear before recessive ones, they both have brown hair

now, lets look at their possible offspring genes

BB Bb Bb bb

in order, their hair color will be

brown, brown, brown, blond

see the last one? the only reason why that child is blond is because they don't have a brown hair gene tldr of this paragraph, recessive genes will only be present if both copies of the gene is the same

with the first example, lets say its a cold day. what would you wear, a jacket or a t shirt? a jacket, obviously

but what if you only had t shirts? then you would be forced to wear that and think about your poor freezing self...

pretend the T shirt is blond hair gene, and jacket is brown hair

and the closet only holds 2 clothes

2 domiant genes will do the same thing, brown hair

1 domiant gene and 1 recessive will use the domiant gene, since domiant genes get used first, like brown hair will show even though you have a copy of blond hair gene

2 recessive genes, and only then will the recessive show, like blond hair

Answer:

Box 1 and box 3

Explanation:

[tex]\huge\boxed{\textbf{Box 1 and Box 3}}[/tex]

[tex]\Large\textbf{Phenotype:}[/tex]

It is the physical appearance of the trait, whether the plant has Long stem or short stem.

[tex]\Large\textbf{Genotype:}[/tex]

A genotype refers to the genetic characteristics of an organism's trait, if it is heterozygous or h o m o-zygous, recessive or dominant. This question is basically based on the Genotype, asking for the heterozygous plants which is a genotypic characteristic.

Allele Long stem A is dominant over short stem a

Pea Plant 1 has genotype Aa

Pea Plant 2 has genotype aa

The question asks for how many heterozygous plants are present in the punnet square of pea plant 1 and pea plant 2.

Heterozygous Plants means those plants which have two different alleles that means One dominant allele (i.e. A here) and One recessive allele (i.e. a here). These Organisms inherit a different version from each parent. In a heterozygous genotype, the dominant allele overrules the recessive one.

If we look at the punnet square given in the attachment, the Box 1 and 3 have genotype Aa which is a HETEROZYGOUS DOMINANT PLANT while box 2 and 4 have a genotype aa which is a HOMO-ZYGOUS RECESSIVE PLANT thus the answer is Box 1 and 3

Producers

Producers are any kind of green plant. Green plants make their food by taking sunlight and using the energy to make sugar. The plant uses this sugar, also called glucose to make many things, such as wood, leaves, roots, and bark. Trees, such as they mighty Oak, and the grand American Beech, are examples of producers.

Primary Consumer

Within an ecological food chain, Consumers are categorized into primary consumers, secondary consumers, tertiary consumers. Primary consumers are herbivores, feeding on plants. Caterpillars, insects, grasshoppers, termites and hummingbirds are all examples of primary consumers because they only eat autotrophs (plants).

Secondary Consumer

Spiders, snakes, and seals are all examples of carnivorous secondary consumers. Omnivores are the other type of secondary consumer. They eat both plant and animal materials for energy. Bears and skunks are examples of omnivorous secondary consumers that both hunt prey and eat plants.

Decomposer

They include fungi along with invertebrate organisms sometimes called detritivores, which include earthworms, termites, and millipedes. Fungi are important decomposers, especially in forests. Some kinds of fungi, such as mushrooms, look like plants.

The correct answer is - dandelion weeds adapted many tricks to reduce all other competitors as it is invasive species.

Explanation:

The dandelion is a successful weed. It's got a lot of adaption to eliminate or dominate other plants and weeds, such as ethylene gas released by its rosette of leaves that prevent other plants from growing near dandelion.

Seeds of dandelion also adapted seed dispersion tactic by seed-parachutes into the wind.  Dandelion weed does not require to be pollinated and rapidly increases their numbers. Dandelion has a taproot that goes deep into the soil, up to three feet down for water and nutrients.

Answer:

a. Serine-Alanine-Isoleucine-Isoleucine-Glycine

Explanation:

This question is describing gene expression, which comprises of transcription and translation. Transcription is the process by which a DNA molecule is used as a template to synthesize a mRNA molecule while in translation, the mRNA is used to synthesize an amino acid sequence using a set of three nucleotide bases called CODON in the mRNA.

According to this question, the following DNA sequence is given: AGTCGCTATTAGCCG. The process of transcription will form the following mRNA sequence from this DNA sequence: UCAGCGAUAAUCGGC.

Translation will make use of the genetic code to produce the following amino acids. Note that, one codon e.g UCA encodes an amino acid (serine).

The amino acid sequence is: Serine-Alanine-Isoleucine-Isoleucine-Glycine.

UCA codes for Serine

GCG codes for Alanine

AUA codes for Isoleucine

AUC codes for Isoleucine

GGC codes for Glycine

Answer:

Composite, shield, cinder cones, and supervolcanoes are the main types of volcanoes.

Composite volcanoes are tall, steep cones that produce explosive eruptions.

Shield volcanoes form very large, gently sloped mounds from effusive eruptions.

Volcanoes have several shapes, which are controlled by the composition of the magma and the nature of its eruption. If a volcano produces very fluid lava (low in the compound SiO2, or silica), the magma flows a long distance before it cools, making a flat, shield-shaped volcano.

Answer:

The transfer of pollen to a stigma, ovule, flower, or plant to allow fertilization. It can be transferred by things that feed from what has pollen. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.
