All of the following are evidence for the big bang except: A. Cosmic background radiation B. Almost all galaxies are red-shifted C. The sound from the bang echoes though the universe D. The universe is expanding

Answers

Answer: C. The sound from the bang echoes though the universe

Explanation:

Cosmic background radiation proves the big bang because it shows that as a result of the big bang, the early universe was really hot but cooled as it expanded. Cosmic background radiation is the result of that earlier heat.

Galaxies being red-shifted means that the space between galaxies is increasing which means that the universe is expanding which provides evidence for a big bang because particles move away the single point they are concentrated in.

There was no actual bang from the big bang and sound cannot echo through space so c is incorrect.

A: Humans have not evolved.
B: Humans, chimpanzees, and other primates share a common ancestor.
C: Gorillas evolved from humans and chimpanzees.
D. Humans evolved from gorillas and other primates.

Answers

Answer:

B: Humans, chimpanzees, and other primates share a common ancestor.

Explanation:

According to the theory of evolution, organisms of a particular species change in their characteristics over several generations because of the process of natural selection. The idea of evolution derives from the fact that all species are related and gradually change over time.

Species which are somewhat related all share a common ancestor. Hence, humans, chimpanzees, and other primates all share a common ancestor.

What is cellular respiration?

Cellular respiration is a succession of chemical reactions that break down glucose to produce ATP, which can then be used as energy to power a variety of reactions throughout the body.

Cellular respiration consists of three major steps: glycolysis, the citric acid cycle, and oxidative phosphorylation.

It is mirror image of photosynthesis, its chemical reaction is:

b. diffusion and osmosis across semi-permeable membranes
c. the movement of the flagella of sperm for motility
d. exocytosis of waste substances across a semi-permeable membrane

Answers

Answer:

b. diffusion and osmosis across semi-permeable membranes

Explanation:

ATP (adenosine triphosphate) is a high energy carrying molecule in the system of living organisms. It posseses the ability to store and release energy for use by organisms during biochemical activities. However, some processes do not require ATP to occur and are called PASSIVE TRANSPORT while those that require energy (ATP) are called ACTIVE TRANSPORT.

In the above options, the processes listed as follows require ATP to occur:

- The active transport of glucose from the small intestine to the blood

- The movement of the flagella of sperm for motility

- Exocytosis of waste substances across a semi-permeable membrane

However, the diffusion and osmosis across semi-permeable membranes, which is a passive transport does not require ATP.

Which type of white blood cell is activated by antigens that are bound to antibodies?
monocytes
eosinophils
basophils
neutrophils

Answers

Answer:

basophils

Explanation:

Basophils are a class of white blood cells known as granulocyte, which also include neutrophils, eosinophils, and mast cells. These cells (basophils) are generated in the bone marrow as other white blood cells. When stimulated, basophils degranulate to release histamine, proteoglycans, and proteolytic enzymes and thus mediate immune responses. This process of degranulation occurs when a specific antigen binds to the IgE receptor on the basophil. Moreover, basophils may also be activated by inflammatory mediators (e.g., complement factors such as C5a and C3a, chemokines, etc).

What are amoebas?

Amoebas are a group of single-celled organisms belonging to the phylum Amoebozoa. They are classified as protists, which are a diverse group of eukaryotic microorganisms that do not fit into the categories of plants, animals, or fungi.

Amoebas are characterized by their ability to move and change shape through the use of pseudopodia, which are temporary extensions of their cell membrane. These extensions allow amoebas to engulf and surround their food, typically consisting of bacteria, algae, or other small organisms.

Amoebas are single-celled protists that move using pseudopodia, which are temporary extensions of their cell membrane.

Answers

Answer:

is expressed roughly equally in both sporulating and nonsporulating yeast

Explanation:

A DNA microarray (also called DNA chip) is a microchip-based testing platform which can be used to analyze and compare gene expression profiles between samples. A DNA microarray contains microscopic DNA spots attached to a solid surface, where each spot corresponds to thousands of copies of a specific DNA sequence (i.e., probes). Subsequently, cDNA 'target' molecules obtained by reverse transcription from RNA are then hybridized to a microarray. This process of hybridization can be quantified by using fluorophore-labeled targets that determine the level of the expressed gene (transcript) in the target sample. In a DNA microarray, the intensity and types of color in each spot indicate the presence and level of each specific transcribed gene in the samples. In consequence, the presence of yellow spots in the DNA microarray indicates approximately equal expression levels of the corresponding gene in both yeast samples.

An individual with two different versions of a gene is genetically ____________ . In traits with a simple pattern of inheritance, only the trait conferred by the ____________ form of the gene will be visible. The other form of the gene is ____________ : it confers a trait that is only visible when the individual is genetically ____________ , or has two identical copies of the gene.

Answers

Answer:

heterozygous; dominant; recessive; h.o.mo-zygous

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

In Genetics, co-dominance can be defined as a phenomenon in which two (2) alleles of the same gene are present in a living organism and both are equally expressed to a degree or simultaneously.

This ultimately implies that, co-dominance is a phenomenon that typically involves the relationship between alleles i.e the two (2) versions of a gene present in living organisms. Also, a single version of a gene expressed by a living organism is referred to as an allele.

Trait can be defined as a distinguishing quality or characteristic of a living thing.

Simply stated, a trait refers to the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her.

Some examples of traits in genetics are colorblindness, handedness, curly hair, height, complexion, weight, hair color, dimples, tongue-roll, etc.

In Genetics, when an individual has two (2) different versions of a gene, he or she is said to be genetically heterozygous.

In traits with a simple pattern of inheritance, only the trait conferred by the dominant form of the gene from the parent organism will be visible in the offspring of a living organism. The other form of the gene is recessive : it confers a trait that is only visible when the individual is genetically , or has two identical copies of the gene.

A sperm fertilized an egg. Which two structures will the fertilized egg contact?
ovary and fallopian tubes

cervix and ovary

Answers

Answer:

B Edge 2021

Explanation:

I just took the test

When a sperm fertilizes an egg, the fertilized egg, also known as a zygote, will travel from the fallopian tube to the uterus, where it will implant and grow into a fetus. Therefore, the correct option is B.

What is a fertilized egg?

A fertilized egg is also known as a zygote. It is a single cell that results from the union of a sperm and an egg during fertilization. Fertilization typically occurs in the fallopian tube of a female reproductive system when a sperm successfully penetrates and merges with the egg.

The egg is released from the ovary and travels through the fallopian tubes towards the uterus. It is in the fallopian tubes where the egg can be fertilized by a sperm, forming a zygote.

The zygote will then continue to travel through the fallopian tube towards the uterus. As it approaches the uterus, the zygote will undergo several cell divisions, forming a ball of cells known as a blastocyst.

The blastocyst will then implant into the lining of the uterus, where it will continue to grow and develop into a fetus. The cervix, which is the lower part of the uterus, plays a role in pregnancy by keeping the fetus inside the uterus during gestation and then opening to allow for delivery during childbirth.

Therefore, option B) the fallopian tubes and uterus is correct.
