Given that the diploid number of cattle is 60 (2n = 60) how many pairs of chromosomes do cattle have?
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.
Give me an example of a producer, primary consumer, secondary consumer, and decomposer within the same ecosystem.
HELP
Answer:
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.

Explanation:
The heart rate increases during exercise. This increase in heart rate increases blood flow to the muscles. Explain, as fully as you can, why this increase in heart rate is necessary.
pls help I am on a timer, think it is biology but not sure
Answer:
Getting your heart beating faster than it's resting rate each day trains your body to move oxygen and blood to your muscles more efficiently. This helps your muscles use that fuel more economically as well, and ultimately you move with more ease. In other words, you end up in shape.
Explanation:
What are three kinds of volcanoes? What makes them different?
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.

how might a virus infect a cell and remian inside the cell without killing it
Answer: As you've learned, some viruses are released when the host cell dies, and other viruses can leave infected cells by budding through the membrane without directly killing the cell.
Explanation:
all Nucleotide elements
Answer:
The phosphate groups allow the nucleotides to link together, creating the sugar-phosphate backbone of the nucleic acid while the nitrogenous bases provide the letters of the genetic alphabet. These components of nucleic acids are constructed from five elements: carbon, hydrogen, oxygen, nitrogen, and phosphorous.
Explanation:
What is pollination? Identify three ways pollen can be transferred. How is cross-pollination different
from self-pollination?
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.

I need help with dominant and recessive genes, it doesn't really make sense to me can sombody explain how it works?
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

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
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.
How does absolute age relate to geologic time?
the age of Rock in years is called its absolute age geologist find absolute age by measuring the amount of certain radioactive elements in the rock

AGTCGCTATTAGCCG
a. Serine-Alanine-Isoleucine-Isoleucine-Glycine
b. Serine-Arginine-Cysteine-Stop
c. Arginine-Leucine-Isoleucine-Alanine-Threonine
d. Alanine-Valine-Cysteine-Arginie-Threonine
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

DNA is the hereditary molecule that determines hair color in humans. However, the DNA molecule itself is colorless. How does DNA determine the hair color of individuals?
Answer:
This question lacks options, the options are:
A. The sequence of DNA determines the structure of lipids, which produce phenotypes.
B. The sequence of DNA determines the structure of proteins, which produce phenotypes.
C. The sequence of DNA determines the structure of phosphates, which produce phenotypes.
D. The sequence of DNA determines the structure of carbohydrates, which produce phenotypes.
The answer is B.
Explanation:
DNA is the genetic material found in the genome of living organisms. DNA holds the information needed for the synthesis of useful products in an organism. DNA contains segments called GENES that encodes the biological molecule, PROTEINS, which is responsible for the trait exhibited by organisms.
An example of trait in humans is human color, which is encoded by DNA. However, this DNA does not directly produce hair color in humans but the information held in it undergoes expression to produce protein called MELANIN, which is responsible for the hair color trait. Hence, the sequence of DNA determines the structure of proteins, which produce phenotypes (hair color).

Which two genes are most likely to be affected by a crossing over event?
A. a pair of genes located adjacent to another on a chromosome
B. a pair of genes separated by a third gene on a chromosome
C. a pair of genes located at opposite ends of a chromosome
D. a pair of genes located on different chromosomes
Answer:
c
Explanation:
becuase a pair of genes located opposite ends on a chromosome
A pair of genes located adjacent to another on a chromosome are most likely to be affected by a crossing-over event (Option A).
Linked genes are genes located on the same chromosome.Crossing over, also known as recombination, refers to the exchange of genetic material between non-sister chromatids during meiosis (Prophase I).During crossing over, linked genes are separated to be recombined between non-sister chromatids, thereby increasing the genetic diversity of the resulting germinal (gamete) cells.In conclusion, a pair of genes located adjacent to another on a chromosome are most likely to be affected by a crossing-over event (Option A).
