A blood specimen X is tested with blood group A serum and with B serum, both of which it agglutinate. To which blood group does X belong?

Answers

Answer 1

Answer: The blood group X belongs to is blood group AB.

Explanation:

Blood group typing is a process used in blood group serology to safely receive or donate blood during transfusion procedures. Blood groups found in human being can be put into four distinct groups, A, B, AB, and O, according to the antigens and antibodies that are found in the blood. Antigens are found on the surface of the red blood cells, while antibodies are found in plasma.

--> Blood group A: They possess A antigen on their red blood cells and antibody B in the serum

--> Blood group B: They possess B antigens on their red blood cells and antibody A in the serum.

--> Blood group AB: They possess both antigen A and B on their red cells with NEITHER antibody A nor B.

--> Blood group O: They possess neither antigen A nor B on their reb cells but has BOTH antibodies A and B.

In blood typing, we can identify our blood group by mixing a drop of blood with serum containing:

--> Anti- A antibody and

--> Anti- B antibody.

The clumping of red blood cells is called agglutination. The anti - A serum will cause the blood containing red blood cells with antigen A to clump while the anti- B serum would cause blood containing red cells with antigen B to clump. Therefore, specimen X is Blood group AB as the blood group contains both antigen A and B which clumps when added both A and B serum antibody.

In a given year, which would result in the greatest increase in population size?

A. high birth rate, high death rate, high immigration, high emigration
B. high birth rate, zero death rate, high immigration, zero emigration
C. zero birth rate, low death rate, zero immigration, low emigration
D. zero birth rate, zero death rate, low immigration, high emigration

Answers

B would definitely result in population rise.

Answer:

B. High birth rate, zero death rate, high immigration, zero emigration

Explanation:

High birth rate would mean more people being born resulting in a higher population. Zero death rate would mean that no one is dying and leaving the population. Immigration means when people come to a foreign country to live there, meaning that the population would grow. Emigration means the opposite of immigration. So that would mean that the people would be leaving your country. Resulting in a lower population. So, B is the correct answer!

how the cells in your body are different from one another. Look at the different types of cells above, and make a list of how they differ. After you have made your list, consider why they have these differences.

Answers

Answer: Different cells have different jobs to do. Each cell has a size and shape that is suited to its job. Cells that do the same job combine together to form body tissue, such as muscle, skin, or bone tissue. Groups of different types of cells make up the organs in your body, such as your heart, liver, or lungs.Differentiation means that one cell performs a different function than another cell, depending on where it is in your body. ... All the cells contain the same genetic material and all of them are from one original cell that started as a fertilized egg, but they look different and act different from one another. Under a microscope, fat cells look like bulbous little spheres. Like other cells in the body, each has a cell membrane and a nucleus, but their bulk is made up of droplets of stored triglycerides, each of which consists of three fatty-acid molecules attached to a single glycerol molecule. Skin cells are specialized to be quickly shed and replaced, and do not have much mitochondria (which helps produce energy). Muscle cells, conversely, have lots of mitochondria because they need energy to produce movement. Unlike many other cells, red blood cells have no nucleus and can easily change shape, helping them fit through the various blood vessels in your body. Unlike most other eukaryotic cells, mature red blood cells don't have nuclei. When they enter the bloodstream for the first time, they eject their nuclei and organelles, so they can carry more hemoglobin, and thus, more oxygen. Each red blood cell has a life span of around 100–120 days. Skin cells are specialized to be quickly shed and replaced, and do not have much mitochondria (which helps produce energy). Muscle cells, conversely, have lots of mitochondria because they need energy to produce movement. brainliest??

During the Human Genome Project, scientists created a gene map showing the relative location of each known gene on every human chromosome. This map led to the discovery that the human genome is made up of about how many genes?

Answers

Answer:

Approximately 20,500 genes

Explanation:

The Human Genome Project (HGP) was a 13-year international research effort aimed at determining the entire DNA sequence of the human genome. The HGP was launched in 1990 and completed in April 2013. This project helped to identify and physically map all the genes of the human genome. The sequence obtained from the HGP has been a very useful point of reference in order to identify and characterize mutations associated with genetic disorders. The HGP predicted approximately 20,500 genes (each of them produces an average of three proteins), which are distributed in the 23 pairs of chromosomes in the cells of our body.

Where a disturbance did not completely wipe out all life and nutrients from the environment, secondary succession occurs and homozygous.

Thus, Despite the fact that fire, flooding, and other disturbances can leave a landscape in ruins, drive many animals and plants away, and bring the biological community back to an earlier stage, the habitat is still alive because the soil still contains nutrients and seeds that were sown before the disturbance.

The homozygous genotypes' two alleles are not expressed over one another in incomplete dominance; instead, an intermediate heterozygote is created.

A significant contributing factor to the variety in the traits or properties of an organism is incomplete dominance.

SS - phenotype; constricted pod - genotype.
SS - genotype; constricted pod - phenotype

Answers

Answer:

ss - genotype; constricted pod - phenotype

Explanation:

trust me Lol

Pea plants having gene control phenotype of pod shape S is dominant having phenotype smooth and phenotype constricted pods having s genotype, hence option d is correct.

What is the difference between genotype and phenotype?

Phenotype is a physical observation of a trait which control by agene

and genotype is a genetic observation that can not be seen physically.

The allele which controls the phenotypic character of a plant is called the dominant over the other allele which can not show its expression, the allele is always present in a group but only the dominant will show its expression.

In a pea plant, if the allele for smooth is dominant over the other, it shows expression in allelic combination and masks the expression of constricted pods.

Therefore SS is the genotype and the constricted pod is the

phenotype, hence option d is correct.

Answers

1. uracil (U) is dna and thymine T is mRNA
2 is an opinion
3 i think polymerases in rna

Answer:

DNA sequences use the nucleotides A, T, G, and C, while mRNA sequences use the nucleotides A, U, G, and C.

It was easier to decode the messages written in mRNA sequences because these sequences could be translated directly into the amino acid sequence.

The cellular enzyme that carries out transcription is RNA polymerase.

The cellular machine that carries out translation is the ribosome, which is composed of both rRNA and ribosomal proteins.

In a eukaryotic cell, an mRNA transcript often has additional untranslated regions and a poly-A tail. A eukaryotic mRNA transcript would need to be transported from the nucleus to the cytoplasm before it could be translated.

Some amino acids are encoded by several codons. If a single nucleotide mutation still encodes for the same amino acid, the resulting amino acid sequence would not be affected. This happens most often with nucleotides in the third position of a codon.

If a single nucleotide mutation changes the amino acid encoded, the resulting amino acid sequence would be affected. This happens most often with nucleotides in the first and second positions of a codon.

Nucleotide insertions and deletions cause frameshift mutations, which change the reading frame of translation and will encode completely different amino acids from that point forward.

There are only 20 canonical amino acids, so the letters B, J, O, U, X, and Z are not used as one-letter codes.

It was a little difficult to not use the letters B, J, O, U, X, and Z at first, but there are messages to write without these six letters.

Biotic and abiotic factors affect population density and dispersion. A) Explain the factors that affect a population's density. B) Describe the types of population dispersion, with examples, and the factors that influence them.

Answers

Answer:

Water supply, climate, shape of the land, vegetation, soils and availability of natural resources.

Explanation:

Water supply, climate, shape of the land, vegetation, soils and availability of natural resources are the factors that affect population density of an ecosystem. There are three types of population dispersion are uniform dispersion, random dispersion, and clumped dispersion. In uniform dispersion, individuals of a population are more or less evenly distributed for example, allelopathy plants. In random dispersion, individuals are distributed randomly in the ecosystem for example, dandelions plants. Clumped dispersion is when individuals in a population are clustered together for example, oak trees.

Answer:

This is an example of parasitism

Ver a long period of time, flower shapes and color variation have changed as a direct response to attract more pollinators, such as bees and hummingbirds. This is an example of Predation. Thus, option A is correct.

What are predators?

A predator is a creature that eats all or a portion of the body of its victim, which may be alive or recently deceased. Predators are distinguished from decomposers, such as fungus and bacteria, which break down the remaining remnants of dead species, by the phrase "living or recently killed."

We can confidently classify a lion as a predator if we witness it devouring a zebra. However, the zebra is included in the wide definition as well! Prey for a predator can include both plants and fungi as well as living things.

Additionally, a predator is not required to kill its victim. Instead, it can just remove a part of the prey's body and leave it alive, like a grazing cow or a bloodsucking mosquito. Herbivory is the term for a predator-prey situation in which an animal or insect eats a plant; herbi- stands for plant, and -vory implies eating.

Therefore the correct option is B.
