Josh and his family always rent a beach
house for summer vacation. One
afternoon, Josh and his Dad took the
boat out and when they returned pulled
up their boat on the beach and went in
to have lunch. When they returned, the
beach was covered in water and the
boat was floating offshore. What is a
likely explanation?
Answer:
The tide had probably rolled in and covered the beach with water and had swept the boat away offshore.
(I'm so sorry if this is wrong)
Hope this helps!
Answer:
High Tide
Explanation:
It seems from the question that after they returned, the beach was covered with water, High tide explains it because the tide is at it’s highest point at that time. Since the water is at it’s highest point, the boat was washed away and the beach was covered with water.
Tell me if this is wrong!

If astronomers discovered a new inner planet in the solar system, which characteristic would it most likely have?
A: large size
B: gaseous composition
C: many moons
D: fast revolution
Answer:
D: fast revolution
Explanation:
As the inner planets rotate around the Sun much faster than the outer ones, the new inner planer would have a fast revolution.
The closer the planet is to the star, the faster is its revolution. Also, the inner planets are smaller, with less density which helps them rotate faster.
Answer: D. fast revolution

Many antelope species, including hartebeest, wildebeest, impala, Thompson's gazelle, and others, live on the African plains and eat many of the same food plants. An increase in the population of any of these species leaves less food for the others. This is an example of what type of relationship?
Answer:
Competition
Explanation:
Competition occurs when many organisms are in search for the same, limiting resource this include food, water,space.
The use of this limited resource by one species decreases availability to the other population especially when there is an increase in population the rate of competition is very high.
Competition reduces the fitness of all the organism and can either be interspecific which is among the same organisms or between different species.

7. Products like "Tums" neutralize stomach acid because Tums is a a. neutral. b. base. c. acid.
Answer:
(B) Products like "Tums" neutralize stomach acid because Tums is a base.
Explanation:
If the product neutralizes an acid, that means it must be a base. Acid + Base = Neutral. If you were to consume an product that is acidic, the stomach will end up being overly acid, which is unsafe for the body. If you were to consume a product that is neutral or "normal", the product would not do as much to neutralize the stomach acid, compared to a more basic pH. Tums has a main ingredient of calcium carbonate, CaCO3, a base. This ingredient helps regulate the pH levels for your stomach so that it does not become too acidic.
In an aerobic cell, active transport is most directly affected by damage to
the
Mitochondria
chloroplasts
Ribosomes
centrioles
Answer:
mitochondria
Explanation:
aerobic is active and energy is produced in the mitochondria so if the mitochondria was damaged it would affect the active transport
In an aerobic cell, active transport is most directly affected by damage to the - Mitochondria as it provides energy for active movement.
Active transport is a movement of particles through the cell membrane against the gradient, or particles too large to move, therefore, they require additional energy to move such substances.
Cellular respiration provides energy for active transport.It takes place in the mitochondria, therefore, cells that perform active transport have many mitochondria.the molecules are moving against their concentration gradient.If mitochondria are damage in a cell there will be no energy formation and as active transport requires energy this process will be affected directly.
Thus, the correct answer is - mitochondria.

If the mRNA sequence is GUACUGUAC, what is the DNA Sequence? __
Please and thank you
Answer:
1. When DNA is duplicated from mRNA which DNA, mRNA uses a U nucleotide instead of T.
2. If the mRNA sequence is GUACUGUAC, the DNA Sequence is CATGACATG.
Explanation:
1. The only thing that changes from a DNA sequence to an RNA sequence is that the thymine (T) in DNA is changed to Uracil (U) in RNA.
2. There should be no Uracil (U) in a DNA sequence–– only ATCG. Just matching with the given pairings.
G can transcribed to C.
C can be transcribed to G.
A can be transcribed to T.
U can be transcribed to A.

Mitosis, a stage in the cell cycle, is important for what reason?
a. division of the nucleus b. removal of cancer cells
c. synthesis of DNA d. division of cytoplasm
Answer:
A. division of the nucleus
Explanation:
Mitosis is a biological process that the cells of all organisms go through in order to replicate and reproduce. It is part of the cell cycle, which is made up of G1, S, G2, and M (mitosis). In G1, the cell is growing; in S, the DNA of the cell is synthesized, or replicated, so we know choice C is wrong; in G2, the cell is being prepared for mitosis; and finally, in M, the cell actually undergoes cell division.
So, we are looking for an answer choice that involves division: either A or D.
At the end of mitosis, there's an additional process called cytokinesis that actually divides the cytoplasm, so the answer can't be D.
Thus, the answer is A.

What would happen if you did an experiment in which the iodine solution was placed in a baggie, and the starch solution was in the beaker?
If the iodine solution was placed in a baggie and the starch solution was in the beaker, and the baggie was then submerged in the beaker, a specific chemical reaction called the iodine-starch reaction would occur.
The iodine-starch reaction is a well-known test used to detect the presence of starch in a solution. Normally, when iodine solution (iodine dissolved in water) comes into contact with starch, it forms a dark blue or black color complex.
This reaction is due to the formation of an inclusion complex between the iodine molecules and the helical structure of starch.

irf4 transcription-factor-dependent cd103 cd11b dendritic cells drive mucosal t helper 17 cell differentiation
The discussion of irf4 transcription-factor-dependent cd103 cd11b dendritic cells drive mucosal t helper 17 cell differentiation is given in the below paragraph-
The predominant migratory DC population in the small intestinal lamina propria (SI-LP) is composed of CD103(+)CD11b(+) dendritic cells (DCs), although it is yet unknown what these cells do in vivo. Here, we show that intestine CD103(+)CD11b(+) DC survival required IRF4 to function (IRF4). Mice with a DC loss in Irf4 showed decreased numbers of helper T 17 (Th17) cells that secrete IL-17 in the gastrointestinal tract and failed to support Th17 cell development in draining mesenteric lymph nodes (MLN) after immunization. Both CD103(+)CD11b(+) MLN DCs and DC-derived IL-6 were selectively decreased in the latter. Immunized Il6(-/-) mice were unable to sustain Th17 cell development in MLN in vivo, although CD103(+)CD11b(+) MLN DCs were able to do so in vitro.
Findings collectively point to a critical function for IRF4-dependent, IL-6-producing CD103(+)CD11b(+) DCs in intestinal Th17 cell development.
What is cell differentiation?The transformation of a stem cell from one type to a differentiated one is known as cellular differentiation. Usually, the cell transforms into a more focused kind. Multiple instances of differentiation take place while a multicellular creature develops from a straightforward zygote to a complex system of tissues and cell types.
As adult stem cells divide and produce completely differentiated daughter cells during tissue repair and normal cell turnover, differentiation continues throughout maturity. In response to antigen exposure, some differentiation takes place. Size, shape, membrane potential, metabolic activity, and signal responsiveness of a cell all undergo significant changes during differentiation.

A plate moves south at a rate of 2 cm/year. How many meters south from its original location will the plate be in 4,000 years? 8,000 meters south 4,000 meters south 200 meters south 80 meters southWhich source of evidence did Wegener use to support his theory of continental drift? fossils magnetic fields satellite mapping warm equatorial climates
Answer:
1. 8000 meters
2. Fossils
Explanation:
1. Rate of southern movement of the plate = 2 cm/year.
In 4000 years, the plate will move a distance of 4000 years * 2 cm/year = 8000 meters
Therefore, the plate will move a distance of 8000 meters south in 4000 years.
2. Wegener in supporting his theory of continental drift used fossils, geologic and glacial evidences. He compared the fossils found in different continents and argued that the presence of fossils of certain animal fossils such as the Lystrosaurus which are found in antarctica, India and South Africa indicates that the continents drifted apart as the Lystrosaurus could not have swam across the ocean to get to these different continents. Also, using geologic evidence by comparing rock structures on opposite sides of the Atlantic ocean, he determined that there were similarities between the rock strata of the Karroo system of South africa with the Santa Carina system in Brazil.
