Answers
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.

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).

Answers
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.

A common genetic mutation that lowers levels of the enzyme cathepsin C severely reduces a person’s ability to ward off periodontitis, or gum disease. The enzyme triggers immunological reactions that destroy diseased cells and eliminate infections
in the mouth. But researchers are developing ways to restore the enzyme to normal levels. Once that happens, we will be able to eliminate periodontitis.
Which one of the following is an assumption on which the argument depends?
(A) Restoring cathepsin C to normal levels is the only way to eliminate periodontitis.
(B) Genetic mutation is the only cause of lowered levels of cathepsin C.
(C) Researchers will soon succeed in finding means of restoring cathepsin C to normal levels.
(D) Persons who do not have the genetic mutation that lowers levels of cathepsin C do not get gum disease.
(E) A person whose cathepsin C level has been restored to normal will not suffer from periodontitis.
Answers
Answer:
(E) A person whose cathepsin C level has been restored to normal will not suffer from periodontitis.
Explanation:
Considering the fact that there may be some other causes of periodontitis aside from the lowered levels of the enzyme.
Therefore, should there be some other causes of periodontitis, hence, it can be concluded the process of restoring the enzyme to normal levels might not be sufficient for eliminating periodontitis.
Hence, the author's argument is solely based on this assumption, and option. Hence, option (E) is the correct answer.

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.

To control the population of insects, if insecticides are used then how it will affect the population of birds?
Answers
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.

Which of the following is the correct Lewis structure diagram for Sodium (Na)? (2 points)
Select one:
a. The letters Na with one dot
b. The letters Na with two dots
c. The letters Na with three dots
d. The letters Na with four dots
Answers
Answer:
a. The letters Na with one dot
Explanation:
An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are basically the building blocks of matters and as such determines or defines the structure of a chemical element.
Generally, atoms are typically made up of three distinct particles and these are protons, neutrons and electrons.
In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.
Valency can be defined as a measure of the combining power of a chemical element with other atoms to form a molecule or chemical compound.
Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Thus, valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others.
Sodium is a chemical element that is found in group (1) of the periodic table and as such it has 1 electrons in its outermost shell. Also, the chemical symbol for Sodium is Na and it has one (1) valence electron.
A Lewis structure can be defined as a structural representation of an atom or molecule by using a dot to show the position and distribution of electron(s) around the atom or molecule.
Hence, the letters Na with one (1) dot is a correct Lewis structure diagram for Sodium (Na) because it has just one (1) valence electron in outermost shell.
For example, the Lewis structure diagram for Sodium (Na) is •Na.

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.

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.
