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
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.

The organism that is an animal-like protist is the amoeba.
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. They are classified as animal-like because of their ability to move and capture food in a similar manner to animals. Amoebas belong to the phylum Amoebozoa and are commonly found in freshwater and soil environments.

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

What is a truck's acceleration if the net external force on the truck is 560 N and it has a total of mass of 1000 kg?
Answer:
0.56m/s²
Explanation:
The above is the correct answer.
Force = mass x acceleration = mg
⇒ F = mg
where F = 560 N, m = 1000kg
∴ g = F/m = 560/1000 = 0.56
∴ acceleration, g = 0.56m/s² (answer)
Force is known to be a push or a pull which actually puts a body to motion or brings a body to rest. It has to do with the interaction between bodies.
Mary determined that 5 pollen grains could fit along the diameter of the field of view of her microscope. If each pollen grain has a diameter of 0.3mm what is the diameter in millimeters of the field of view of Mary's microscope
1.5mm
15mm
4.7mm
5.3mm
Answer:
1.5mm
Explanation:
According to this question, Mary is trying to view 5 pollen grains under her microscope. She found out that the 5 pollen grains each with a diameter of 0.3mm could fit along the diameter of the field of view of her microscope.
This means that the diameter of the field of view of Mary's microscope can be calculated as follows:
Diameter of each pollen × no. of pollen that fit in
= 0.3mm × 5
= 1.5mm
Hence, the diameter of the field of view of Mary's microscope is 1.5mm.
Match the surface to its respective albedo score. fresh snow soil ocean (high-angle sun) ocean (low-angle sun) 0.95 arrowRight 0.2 arrowRight 0.9 arrowRight 0.05 arrowRight Reset Next
Answer:
fresh snow → 0.9soil → 0.2ocean (high-angle sun) → 0.05ocean (low-angle sun → 0.95Explanation:
Albedo is the radiation reflected by the earth´s surface to the universe.
Albedo might be defined as a relation between reflected light from a particle and the incident light. It is the fraction of the incident radiation that is reflected by any object. If the surface is mostly clear and clean, most of the incident radiation is reflected. But if the surface is dark and rugose, most of the incident radiation is absorbed, and the temperature of the absorbing object will increase.
Albedo value is always inferior or equal to one and can be expressed as a percentage. The surface that reflects 100% of the incident light will have an albedo value = 1. But if the surface absorbs all the radiation and does not reflect any percentage, the albedo value = 0. Note: there is no real object that might reflect or absorb 100% of the incident radiation.
The importance of albedo is that it avoids high temperatures on the earth. There are many different surfaces with different albedo values. Global variations in albedo are natural processes due to exogenic and endogenic variations. But to these natural events, we must add all the variations caused by human beings´ actions, which increase greenhouse gases, decreasing albedo, and increasing global warming. The increase of greenhouse gases, such as CO₂, decreases albedo. The same occurs with atmospheric dust due to volcanic eruptions. Additional material interposes between the earth´s surface and the universe, decreasing the energy return to the universe.

What might happen to the genes that break down carbohydrates when cats eat lipids and fats, but no carbohydrates?
Answer:
Goes into resting position.
Explanation:
The genes become dormant or in resting position that break down carbohydrates when cats eat lipids and fats, but no carbohydrates because of no use of that genes. The genes can't give instructions to the hormones that produces enzymes which take part in the digestion of carbohydrates so due to no need for the genes of carbohydrates, the genes goes into resting position until carbohydrate is eaten by the cat.
Which type of white blood cell is activated by antigens that are bound to antibodies?
monocytes
eosinophils
basophils
neutrophils
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).

To control the population of insects, if insecticides are used then how it will affect the population of birds?
Answer: Birds are exposed to insecticides through ingestion by mistaking, they ingest pesticide residues when they trim their feathers with their beaks or may drink or bathe in contaminated water. The effects can range from death due to poisoning to a variety of effects such as weakening of eggshells, deformation and slow growth of chicks, lack of appetite, weight loss, immune system damage, hormonal disruption. In addition, insect-eating birds are at a loss when insecticides cause a drop in the number of insects available, especially when they have chicks to feed.
Explanation:
Insects are a class of invertebrate animals characterized by having one pair of antennae, three pairs of legs and two pairs of wings (which, however, may be reduced or missing). They comprise the most diverse group of animals on Earth with an estimated thirty million undescribed species, potentially representing more than 90% of the life forms on the planet. Moreover, they can be found in almost every environment on the planet, so they are not only highly diverse, but also incredibly abundant.
Like any species on the planet, insects play a vital role in the ecosystem, so that a change in the population can compromise the survival of everything around them. On the other hand, insects called "pests" are those insects observed in systems and whose populations cause damage to crops. Although both beneficial insects and pest insects are part of any ecosystem and are also present in human-managed systems. Humans combat these pests using insecticides, which are chemical compounds used to kill insects. They are usually very specific since the product only affects the organism it damages, leaving the rest of living beings and the environment unharmed. And they have low toxicity to humans and animals.
The most common way in which birds are exposed to insecticides is through ingestion by mistaking, for example, a pesticide granule for a seed, or indirectly, by consuming contaminated prey (insects). Birds may also ingest pesticide residues when they trim their feathers with their beaks or may drink or bathe in contaminated water. It should be noted that it also depends on the toxicity of the chemicals, the magnitude and duration of exposure. The effects can range from death due to poisoning to a variety of effects such as weakening of eggshells, deformation and slow growth of chicks, lack of appetite, weight loss, immune system damage, hormonal disruption. In addition, insect-eating birds are at a loss when insecticides cause a drop in the number of insects available, especially when they have chicks to feed.

Answer:

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.
