Answer:
D. 3:1
Explanation:
Gregor Mendel, in one of his numerous studies, performed a cross between purebred dominant (TT) pea plants and purebred recessive (tt) pea plants. All the offsprings of this cross appeared heterozygous tall (Tt) in the F1 generation.
However, when he self-crossed the F1 generation i.e. Tt × Tt, Mendel obtained a phenotypic ratio of 3 tall plants (dominant traits) : 1 short plant (recessive). This showed that the masked gene (recessive) was still present.

The history of life has been punctuated by several mass extinctions. For example, the impact of a meteorite may have wiped out most of the dinosaurs and many forms of marine life at the end of the Cretaceous period. Fossils indicate that plants were less severely affected by this mass extinction. What adaptations may have enabled plants to withstand this disaster better than animals
Answer:
Due to dormancy.
Explanation:
Plants have an advantage in surviving mass extinction because Plant seeds can remain dormant for many years in the soil without damaging and comes out from the soil when the conditions of the external environment become suitable. Plants can remain in dormant condition for a large period of time while on the other hand, animals have no such type of advantage so that's why plants survive mass extinction.
Noah wants to show the largest source of carbon on Earth for his school project. According to his research, in which form is most of the carbon on Earth stored?
Noah wants to show the largest source of carbon on Earth for his school project. According to his research, most of the carbon on Earth is stored in the form of
.
Answer:
The majority of carbon on Earth is found in rocks and sediments, with the remainder found in the ocean, atmosphere, and living creatures. Carbon cycles pass through these reservoirs, or sinks.
Explanation:
For his school project, Noah wants to demonstrate the earth's natural primary carbon-producing source. His results suggest that sedimentary rocks are where the majority of the carbon on earth is preserved for future use.
What is sedimentary rock?The gradually building or deposition of mineral or organic particles at the Earth's surface, followed by cementation, is the process by which sedimentary rocks are formed. Sedimentation is the broad term employed to define the procedures which lead to the accumulation of these particles.
Sedimentary rocks are constructed from pre-existing rocks or remnants of extinct creatures. They emerge from deposits that amass on the Earth's surface. Apparent bedding or layering is particularly common in sedimentary rocks.
Thus, his results suggest that sedimentary rocks are where the majority of the carbon on earth is preserved for future use.

Under normal conditions the sympathetic division is usually active in the body resting heart rates are influenced by nor epinephrine the parasympathetic system keeps heart rate lower than the heart would beat on its own. all of the above are true
Answer:
the parasympathetic system keeps heart rate lower than the heart would beat on its own.
Explanation:
The parasympathetic nervous system (PNS) is one division of the autonomic nervous system. The vagus (parasympathetic) nerves that innervate the heart release acetylcholine in order to slow the heart rate by decreasing the slope of the pacemaker potential. Acetylcholine activates a type of G-coupled protein receptor known as muscarinic receptors, allowing for a parasympathetic reaction in the cardiovascular system (where these receptors are expressed), and thereby decreasing cardiac output by inhibiting heart rate. During rest, PNS predominates and controls the heart rate at a resting rate of 65-80 beats/minute (bpm), if parasympathetic nerves to the heart are cut, then the heart beats at its own rate of about 100 bpm.

How do scientists classify intrusive igneous features?
according to shape, texture, and their distance from the nearest volcanic field
according to shape, color, and their relationship to surrounding layers of rock
according to shape, size, and their relationship to surrounding layers of rock
Answer:
according to shape, size, and their relationship to surrounding layers of rock
Explanation:
Intrusive igneous features are those formations around the igneous rock that are developed over time when magma cools and forms a solid shape, and they may include stocks, sills, di.kes, etc.
Therefore, scientists classify intrusive igneous features according to shape, size, and their relationship to surrounding layers of rock.

Which is NOT an immune component that can directly attack & destroy target cells?
a. macrophages
b. cytoxic T cells
c. helper T cells
d. natural killer cells
Answer:
Macrophages are part of your innate immune system, which is antigen-independent and does not require activation.
Explanation:
Macrophages phagocytize (internalize) all non-self pathogens it encounters. These do their job without activation. Other cells in the innate immune system include basophils, neutrophils, eosinophils (these cells are polymorphonuclear leukocytes), mast cells, and dendritic cells, which act as the bridge between your innate and adaptive immune system.
All of the other entities listed above are part of your adaptive immune system. The adaptive immune system is antigen-dependent and requires activation. This section of your immune system responds differently to different pathogens, and has the bonus of having immunologic memory, the ability to remember pathogens after infection and respond much quicker upon secondary and tertiary encounters.
Note: All lymphocyte types begin as naïve cells, which then differentiate into their fully matured form upon activation.
Helper T cells are a type of CD4+ T cell that has the job of activating B and T lymphocytes. There are two different types of T helper cells: Th1 and Th2. Th1 cells secrete the cytokine interferon-gamma (IFNγ), and is primarily involved with the stimulation and activation of cytotoxic T cells, while Th2 cells secrete a variety of cytokines and are responsible for activating and assisting with B cells to make antibodies. To make a long story short, Th cells interact with APC (Antigen Presenting Cells), specifically their Class II MHC (a group of genes that present exogenous proteins). The Th cells then proliferate and gain the ability to activate these APC cells and provide the necessary signals to activate B and T cells and make them proliferate and do their specific function.

As with most fluid samples sent for microbiological analysis, Mandy starts her investigation with a Gram stain.
Gram Stain Analysis Classify the infectious agent based on the Gram staining.
Hi. Unfortunately your question is incomplete and you have not shown any photos of the sample that Mandy must identify by Gram stain. However, after researching her question on the internet, I was able to find another question exactly like this one, which showed the microorganism that should be analyzed. This image is attached below. In that case, I hope the answer below can help you.
Answer:
Gram-positive cocci
Explanation:
It is possible to identify that the microorganism presented is a bacteria due to the application of the test known as Gram stain, which allows the identification of gram positive and gram negative bacteria. This test allows the bacteria to be subjected to a specific dye that reacts with the chemical composition of the bacteria, modifying its color. Gram positive bacteria show a blue color after the test, while gram negative bacteria show a red color after the test.
As we can see in the attached image, the bacteria that Mandy is analyzing shows a blue color, after being submitted to Gram stain, being then a gram positive bacteria.
We can also see that the colonies of this bacterium have formed round, similar to a coconut and for this reason, we can conclude that the bacterium has the shape known as cocci.
Therefore, we can classify the microorganism as a Gram-positive cocci.
At this point, the writer is considering adding the following sentence. Successful nerve impulse transmission depends not only on myelin sheaths, but also on the presence of ion pumps embedded in the cell membrane. Should the writer make this addition here?
A) Yes, because it describes how the presence of ion pumps is related to the functions of cholesterol.
B) Yes, because it supports the passage’s main argument with a second example of cholesterol’s potential adverse health effects.
C) No, because it identifies a relationship between the nervous system and ion pumps that has already been discussed.
D) No, because it interrupts the paragraph’s discussion of cholesterol’s functions with loosely related information.
Answer:
D) No, because it interrupts the paragraph’s discussion of cholesterol’s functions with loosely related information.
Explanation:
The passage was discussing the importance of cholesterol in nerve impulse transmission. Its presence in the myelin sheaths of nerve cells speeds up nerve impulse transmission. It will not be wise for the author to now bring in the relationship between nerve impulse transmission and ion pumps. This is because the main topic under discussion is cholesterol and its importance. The sentence should be continued with other importance of cholesterol and not ion pumps.

6.Two apparently normal parents have a daughter who suffers from agammaglobulinemia (AGG), an inherited defect of the immune system. Use a Punnett square to show how two normal parents could have a child afflicted with an inherited disease. What are the parents' genotypes
Answer:
See the answer below
Explanation:
For two normal parents to have produced a daughter who suffers from AGG, it means the disorder is an autosomal recessive trait. In order words, it means the parents are both carrying the allele for the disorder in recessive form.
Let us assume that the allele for the disorder is represented by b, meaning that the alternate form would be B. Both parents will have the genotype Bb and will both appear normal.
Bb x Bb
BB Bb Bb bb
The affected child would be the one with bb genotype while the remaining children would appear normal. See the attached image for the Punnet's square analysis of the cross.
The genotypes of the parent would be heterozygous.
why do sun spots appear darker than their surroundings
Answer:
they are comer than their surroundings.
Sunspots are cooler because their magnetic fields inhibit the replenishing of heat from convective flows (due to the interaction between plasma and magnetic fields). This allows them to cool radiatively. The rest of the solar surface is constantly being replenished by convective cells that reheat it.
Answer:
because they are significantly cooler than the rest of the Sun's surface Despite their gloomy appearance, they are nonetheless extremely hot. A sunspot would shine brightly if it were alone in space.
