Resources (food, water, sunlight, space, and mineral nutrients) drive an organism's survival and adaptation within an ecosystem via metabolic processes and physical structures. A suitable habitat, defined by factors like climate, elevation and geography, determines which organisms can thrive. Hence, both resources and habitats significantly influence an organism's nutritional and reproductive strategies.
Explanation:Resources such as food, water, sunlight, space, and mineral nutrients are vital to organisms as they provide the energy for metabolic processes and the matter to make up an organism's physical structures. This competition for resources, a characteristic of natural selection, occurs both within a single species and between different species.
Moreover, a suitable habitat is equally essential for an organism's survival. Factors such as a habitat's climate, elevation and geology can significantly influence which organisms can thrive in that particular area. For instance, in aquatic biomes, the movement of water impacts the availability of nutrients and food resources.
Essentially, the availability of resources and a suitable habitat directly influence an organism's nutritional and reproductive strategies, thereby affecting its survival and adaptation mechanisms in an ecosystem.

brown bears gain weight during the summer months so they can hibernate during winter. is it adaptation or acclimation
Explains how brown bears gaining weight for hibernation is an example of adaptation, utilizing fat reserves for survival during winter.
Brown bears gaining weight during summer to hibernate in winter is an example of adaptation. This behavior allows them to store energy reserves in the form of fat to survive months without food during hibernation.
Grizzly bears, like polar bears, accumulate fat during summer when food is plentiful and rely on it as an energy source when hibernating in winter. This process exemplifies how animals adapt to changing environmental conditions.
In biomes with cold climates, animals like bears utilize insulation in the form of fur and fat as a survival strategy to endure harsh winter conditions.
Consider the following food chain: garden plants are eaten by snails, which are eaten by birds, which are eaten by the household cat. What happens to the other members of the food chain if the cat is removed?
If the cat is removed the population of birds will escalate and exceed the population of the snails that sustain them.
The food chain is a depiction of the feeding relationship that exists in an ecosystem. An ecosystem is a self-supporting unit in which materials and energy are exchanged.
The food chain is as follows;
garden plants --> snails ---> birds --->household cat. We can see that removal of the cat means that the population of birds will escalate beyond the available population of snails. This will lead to competition for food among the birds within the ecosystem. The population of snails will suddenly decrease due to increase in the number of their predators. The number of garden plants will also increase due to the decrease in snail population.

what observable characteristic could be used to identify this rock sample as gneiss
Gneiss can be identified by its foliated texture with alternating bands of light and dark minerals, and sometimes eye-shaped quartz masses known as augen; it is a high-grade metamorphic rock formed from schists or granites.
Explanation:The observable characteristic that could be used to identify a rock sample as gneiss is its distinct foliated texture. Gneiss is a high-grade metamorphic rock characterized by alternating bands of light and dark-colored minerals, typically quartz and biotite mica. The surface of gneiss may also feature augen, which are eye-shaped masses of quartz that give rise to the term augen gneiss. This rock typically forms from the metamorphism of schists or granites and is a product of high-grade metamorphism, where minerals have segregated into distinct layers due to intense heat and pressure.
Final answer:
The observable characteristic that can be used to identify the rock sample as gneiss is the presence of alternating bands of light- and dark-colored minerals.
Explanation:
The observable characteristic that can be used to identify the rock sample as gneiss is the presence of alternating bands of light- and dark-colored minerals. Gneiss is a high-grade, foliated metamorphic rock, and these alternating bands are a result of the intense metamorphism that has caused minerals to self-segregate into discrete zones. In the case of gneiss, the bands are often composed of minerals such as quartz and biotite mica.

Meiosis is responsible for which stage in the alternation of generations?
A. Gametophyte to sperm
B. Egg to zygote
C. Sporophyte to spore
D. Zygote to mature sporophyte
E. Spore to mature gametophyte
Final answer:
Meiosis facilitates the transformation of the diploid sporophyte into haploid spores in plant life cycles, playing a critical role in the alternation of generations and genetic diversity.
Explanation:
The question relates to the role of meiosis in the alternation of generations within the life cycle of plants. In the context of alternation of generations, meiosis is responsible for transforming a diploid sporophyte into haploid spores. After reaching maturity, the diploid sporophyte undergoes meiosis to produce haploid spores, which then divide by mitosis to produce the haploid gametophyte, thereby continuing the cycle of alternation of generations. This process is essential for maintaining genetic diversity and is a fundamental aspect of plant reproduction.
Therefore, the answer to the question 'Meiosis is responsible for which stage in the alternation of generations?' is C. Sporophyte to spore.

state one change in the composition of the blood as it flows through the respiratory system
Answer:
Respiratory system includes respiratory passage and respiratory organ i.e lungs.
Explanation:
The transport of gases occurs via blood medium. The deoxygenated blood is transported from heart to the lungs for exchange or oxygenation. As the blood flows through the respiratory system the carbon dioxide is exchanged with oxygen. The oxygenated blood is then transported to heart for further circulation to various body parts. Some amount of gases get dissolved in the blood plasma and transported, whereas some amount is transported in the bound state. Oxygen and CO2 bind with hemoglobin in RBC.

All living things are made of one or more cells. Here are two types of cells: an animal cell and a plant cell. Sometimes when plants are under water stress, they wilt. Animals do not wilt! What analogy based on the plant cell structure explains wilting?
Answer:
Presence of cell wall around the plant cells.
Explanation:
An adequately hydrated plant cell is firm due to presence of turgor pressure. Loss of water results in loss of turgor and the plant cells become limp and exhibit wilting. Irrespective of loss of turgor, presence of rigid cellulosic cell wall around the plant cells maintain their structural integrity.
On the other hand, animal cells do not have cell walls around them which in turn do now allow them to maintain the structure after loss of water.

what happens a few days after fertilization (apex)
After fertilization, the conceptus forms a morula and then develops into a blastocyst that implants into the uterus. The outer cells of the blastocyst become the chorion, which releases hormones to support the developing embryo.
Explanation:Approximately 3 days after fertilization, the conceptus reaches the uterus and forms a structure called the morula. This compact mass of cells continues to divide and forms a ball of approximately 100 cells, known as a blastocyst. The blastocyst then implants into the wall of the uterus, and the outer cells develop into the chorion, which releases hormones to maintain the endometrium and support the developing embryo.
The blastocyst is a more complex structure, consisting of two distinct cell layers: the inner cell mass, which will give rise to the embryo, and the outer layer called the trophoblast. The trophoblast further differentiates into the chorion, which is a membrane that surrounds the developing embryo.
The chorion plays a crucial role in pregnancy. It releases hormones, including human chorionic gonadotropin (hCG), which helps to support the early stages of pregnancy by maintaining the corpus luteum in the ovary. This ensures a continued supply of progesterone, which is essential for sustaining the uterine lining and supporting the developing embryo.

Three students each added equal volumes of pond water to four beakers and placed each beaker in a different water bath. Each student maintained the water baths at temperatures shown in the data table below. The students then added an equal number of water fleas to each of the four beakers. After one hour, the students used microscopes to determine the average heart rate of the water fleas. The procedure was repeated for a total of three trials at each temperature. The results of the investigation are summarized in the data table below.
Which component of the experiment above is the independent variable?
number of trials
water temperature
average water flea heart rate
number of fleas per beaker
Answer:
water temperature
Explanation:
When performing a scientific experiment, you need to know what the dependent and independent variables are.
An independent variable is one that influences, causes a result in the dependent variable. This variable does not depend on any factor to be established.
The dependent variable, on the other hand, depends on the independent variable to be established. This is because this variable only shows one result, in relation to the influence that the independent variable had on it.
In the question above, we can see that the students were wanting to determine what the influence of water temperature was on the average heart rate of water fleas. With that, we can say that the water temperature is the independent variable.
