Explanation:
Which of the following is an example of a plant responding to the external stimulus of gravity?
A.) A seedling growing toward a sunny window
B.) A plant root growing down into the soil
C.) Flowers producing nectar to attract bees
D.) a potted plant wilting when it dries out
Answer:
b
Explanation:
bcs the root grows towards the gravity
Answer:
D
Explanation:
In a plant, leaf color and leaf shape are controlled by two linked genes. Leaves of the wild plant are red (R) while a recessive mutation in this gene causes leaves to be white (r). Wild-type leaves are pointed (P), while a recessive mutation in this gene causes them to be smooth (p). For a parent plant that is heterozygous for both traits with both recessive mutations on one chromosome, what genotypes will its gametes be
Answer:
The genotypes of the gametes are:
RP (parental), rp (parental), Rp (recombinant), rP (recombinant)
Explanation:

What is the role of energy in living organisms? Is ti a mor or less important role than other characteristics of life?
Answer:
A huge number of chemical reactions take place continuously in a living cell. The whole of all chemical processes, that is, the total turnover of matter and energy is called metabolism.
Explanation:
All organisms need the energy to grow, reproduce, and respond to their surroundings. All these processes are achieved through metabolism that allows the energy available to them.
How are the graphs of a body chemical controlled by negative feedback and a chemical controlled by positive feedback similar and how are they different
Answer:
two examples of positive feedback loops that are normal but are activated only when needed. Childbirth at full term is an example of a situation in which the maintenance of the existing body state is not desired.
Explanation:
1. Provide two examples of why coral reefs are important ecosystems on Earth.
2. Some corals in the warm pools off Ofu Island can withstand temperatures of 32° to 34 °C without bleaching. So, the researchers set up a controlled laboratory experiment to try to determine why these corals survive in such excessive heat. With regard to the experimental design, provide two reasons why Dr. Palumbi devised a standardized test for the corals.
Answer:
It provides shelter and protection.
Explanation:
Coral reefs are very important to our ecosystems on Earth because it provides shelter to a large population of ocean life and also provide protection to coastlines from strong ocean currents and high waves from causing damage. Dr. Palumbi devised a standardized test for the corals in order to find out that why coral reef can withstand temperatures of 32° to 34 °C without bleaching.

What might happen to your local hydrosphere and geosphere if conditions in the atmosphere caused rain for several weeks?
Answer:
the hydrosphere(bodies of water)would cause floods and other natural disasters while the geosphere will become infertile and landscape change (weathering).
Explanation:
Megalodon left an awful lot of teeth behind, but don't worry. It is likely that it had plenty of extras. Like modern sharks, Megalodon had several rows of teeth. Scientists believe that Megalodon had six rows of 7-inch-wide, razor-sharp teeth, top and bottom, for a total of 276 teeth in its giant jaws! It's no wonder, then, that this ancient shark left so many of them behind. Without this trail of teeth, we would not know that these enormous creatures swam the ancient oceans as a top predator.Select two sentences from below that best show that the author wants the reader to be able to relate Megalodon's size to everyday life
A.What would you expect a creature whose name means “big tooth” to look like?
B.The Megalodon shark deserves this title.
C.As the Greek roots mega- (“big”) and don (“tooth”) suggest, this awesome prehistoric creature certainly did have huge teeth—as well as a massive and powerful body.
D.Scientists estimate that these gigantic sharks stretched as long as 60 feet.
E.If you're having trouble imagining that, just think of a school bus, typically about 45 feet in length.
F.Now, imagine a shark just a bit larger than that school bus—with 7-inch teeth.
G.Yes, this ancient fish certainly earned the prefix mega!
H.Since these sharks are extinct, how do we know exactly how huge and powerful the Megalodon shark was?
The answer is D and F. I did the test

Abstract
Feeling connected to nature has been shown to be beneficial to wellbeing and pro-environmental behaviour. General nature contact and knowledge based activities are often used in an attempt to engage people with nature. However the specific routes to nature connectedness have not been examined systematically.
Explanation:
electrons are the electrons in the outer energy
level of an atom that can participate in interactions with other
atoms.
Check it
Answer:
Valence
Explanation:
In an atom, the electrons at the outermost energy level is called as valence electrons. It is the valence electrons which participates and interacts with the other atoms and form bonds. The valence electrons of an atoms are important as they depict the chemical properties of an element.
Thus the valence electrons resides the outermost shell and surrounds the atomic nucleus.
What process lead to biological nitrogen fixation?
What is an organ system? Choose one of the organ systems and list the organs that belong to that system, as well as the system’s function.
Answer:
An organ system is a group of organs that work together as a biological system to perform one or more functions. Each organ does a particular job in the body, and is made up of distinct tissues.
1 circulatory system.
Circulates blood around the body via the heart, arteries and veins, delivering oxygen and nutrients to organs and cells and carrying their waste products away.
Keeps the body's temperature in a safe range.
Answer:
There are ten major systems in the organ system.
One Example:
renal system, in humans, organ system that includes the kidneys, where urine is produced, and the ureters, bladder, and urethra for the passage, storage, and voiding of urine.
Explanation:
A system is an organization of varying numbers and kinds of organs so arranged that together they can perform complex functions for the body. Ten major systems include the skeletal, muscular, nervous, endocrine, cardiovascular, lymphatic, respiratory, digestive, urinary, and the reproductive system.
Sponges, members of the phylum Porifera, are sessile filter feeders that lack tissues or organs. Instead, specialized cells have unique functions like ingesting food, support, and reproduction. Such specialization within a sponge body is a result of
A) cytokinesis.
B) cell cleavage.
C) cell differentiation.
D) gamete fertilization
Answer:
C) cell differentiation.
Explanation:
Cell differentiation is a process undergone by a cell in which it changes to a specialized form. During the process of cell differentiation, some genes in a single cell becomes turned off or on in a process called GENE EXPRESSION to give rise to cells with specialized functions.
This is the case of this sponge whose specialized cells perform unique functions like ingesting food, support, and reproduction. The specialization of the cells within the sponge is as a result of the process of CELL DIFFERENTIATION.

The movement of organisms from one place to another is called ___________. *
Answer:
Dispersal
Explanation:
It refers to the group of ecosystem sharing the same climate
Answer:
The correct answer is - Biome.
Explanation:
A biome is large area with a particular climate in this region of the earth and typical animals found in the particular area. Biom have different group of ecosystem present in it but live together in a particlular or same climate.
All plants and animals found in every biome has advantage as biome have specific traits like temerature, precipitation, sunlight or humididty and mnymore that help in surviving. For instance, polar bear will live only low humidity and low temperature.
