Answer:
Coasts are sensitive to sea level rise, changes in the frequency and intensity of storms, increases in precipitation, and warmer ocean temperatures. In addition, rising atmospheric concentrations of carbon dioxide (CO2) are causing the oceans to absorb more of the gas and become more acidic.

Which type of growth occurs when population growth slows or stops after a period of exponential growth?
decreasing
exponential
linear
logistic
Answer:
D. Logistic
Explanation:
edge 2002 :)
The type of growth that occurs when population growth slows or stops after a period of exponential growth is logistic growth.
What is logistic growth?Logistic growth is a type of population growth that occurs when the population initially increases exponentially but eventually reaches a carrying capacity and levels off. In logistic growth, the population growth rate slows down as it approaches the maximum sustainable population size that the environment can support.
Initially, in a resource-rich environment, the population experiences exponential growth, where the growth rate is proportional to the population size. However, as the population approaches the carrying capacity, resources become limited, competition for resources increases, and factors like predation, disease, and space availability come into play. These factors lead to a decrease in the growth rate, eventually reaching a point where the birth rate equals the death rate, resulting in a stable population size.
The logistic growth curve is S-shaped, with rapid growth in the early stages, followed by a gradual tapering off as it approaches the carrying capacity.

Where do plants get the carbon needed to make glucose molecules during the process of photosynthesis?
Answer:
From CARBONDIOXIDE (CO2) found in the atmosphere
Explanation:
Photosynthesis is a process performed by autotrophic organisms like green plants. It is a phenomenon whereby these plants manufacture their own food (sugars) using an inorganic carbon source in the presence of sunlight to provide energy.
The major end product of photosynthesis is glucose, which has a carbon constituent i.e. C6H12O6. However, this carbon needed to make glucose is got from an inorganic molecule called CARBON DIOXIDE, which the plants take from the atmosphere in via the stomata on their leaves.

Which geologic term or phrase explains why the reason rock layers typically form parallel to each other? Cross-cutting relationships Original horizontality Superposition Unconformities
Answer:
Original Horizontality Principle is the Relative Chronology Principle which states that sediments are always deposited in horizontal layers. Any geological phenomenon that changes the horizontality is always after sedimentation.
Explanation:
Answer:
Original Horizontally
Explanation:
First of all, the principle of original horizontality explains why sediments form horizontal and parallel layers. Rocks broken down by weathering are distributed according to how they retain the least energy.
2. Scientists use the term "unconformity" to refer to a place in a body of rock where rock is missing. Unconformities lead geologists to hypothesize about past events, but they may not be able to find conclusive proof for their hypotheses. Some types of rock weather more quickly than others, further complicating the analysis of rock layers.
3. According to the Law of Superposition, the bottom layer is generally the oldest layer of rock. Therefore, fossils found in the lower strata are older in relation to fossils found in higher rock layers.
4. Picture Below (at the end it mentions cross-cutting relationships)

2) cream - 25%

3) co-dominance
Explanation:
Ok so a run down on Punnett Squares, all you have to do is put the parent's genes on the top and right hand side and combine those two genes in the middle as I did in the picture. Now, co-dominance, this basically means that there is no dominant allele. For example, imagine a white flower (W) and a red flower (R). If these two plants were to breed, you would get a pink flower (WR). This means the red allele and the white allele are both co-dominant. It is basically a combination of both genes that result in a mixed phenotype of the two genes, aka red and white makes pink. This is also how you get an AB blood type.

What will happen if if you plant a seed ,keep it in a dark corner,and do not water it?Science grade 1
Answer:
to tell you the truth buddy it will die because it is not getting in sunlight or water to make photosynthesis so there for it can not grow at all
Explanation:
If you plant a seed and keep it in a dark room without regular watering it. You will soon find that it will eventually die off because the seed is not getting the components of photosynthesis in order to derive energy.
What are the components required for the seed to grow?The components that are significantly required for the seed in order to perform normal growth are water, oxygen, proper temperature, and sunlight. When they meet all these criteria, they germinate as usual.
According to the context of this question, all seeds and even plants must significantly need components of photosynthesis in order to derive energy that accomplishes all sorts of metabolic purposes and growth and development.
Therefore, if you plant a seed and keep it in a dark room without regular watering it. You will soon find that it will eventually die off because the seed is not getting the components of photosynthesis in order to derive energy.

Human body cells each have 46 chromosomes in their nuclei. Meiosis is necessary in order to ensure that each gamete produced in the human body has —
12 chromosomes
23 chromosomes
46 chromosomes
92 chromosomes
Answer:
B) 23 chromosomes
Explanation:
46 ÷ 2 = 23
To ensure so each gamete created inside the human body contains 23 chromosomes, meiosis is required.. So, the correct option is B.
What is Meiosis?In sexually reproducing organisms, meiosis is a unique form of division of germ cells that results in the production of gametes, including such sperm or egg cells. Two rounds of duplication are necessary, and the end product is four cells with just one duplicate of each chromosome.
Consequently, meiosis produces four haploid daughter cells that are each genetically distinct and have half the DNA of a parent cell The parent cell of a human cell has sets of chromosomes (23 pairs which are 46 chromosomes), hence the cells created during meiosis have 23. Gametes will develop from these cells. To ensure so each gamete created inside the human body contains 23 chromosomes, meiosis is required.
Therefore, the correct option is B.

What is the locomotory structure of yeast
Answer:
Yeast cell structure
Each yeast cell has a distinct cell wall enclosing granular cytoplasm, within which can be seen a large vacoule and a nucleus (Fig. 214). The vacuole varies much in size according to the state of activity of the cell.
Yeast contains almost the same organelles of a mature eukaryotic cell. Nucleus, Golgi apparatus, mitochondria, endoplasmic reticulum, vacuole, and cytoskeleton are the most important one. Yeast cell particle size is typically of 5×10μm.
Explanation:
Yet, we don't always think of yeast as something remarkable. Instead, it's often perceived as plain or dull—a single-celled organism that, like a plant, lacks the ability to move on its own accord.
