A natural resource is best defined as any naturally occurring material that is which of the following?
A. Used by people
B. Mined from Earth
C. Unlimited in quantity
D. Left untouched in nature
Answer:
The correct answer is B
Explanation:
A natural resource will always come from nature and it can be used for economic gain.
Yes, they can be used by people, but so can other resources, so the answer is not A.
Not all natural resources are unlimited, such as coal, are unlimited in quantity, so the answer is not C
Lastly, we do not leave natural resources untouched; we use them, so the answer is not D.

Carrying capacity is Group of answer choices seldom reached by marine producers and consumers because of the vast resources of the ocean. the maximum population size that a particular environment can support. fixed for most species over most of their range most of the time. the term used to describe the stress a population undergoes due to limited resources.
Answer:
the maximum population size that a particular environment can support.
Explanation:
A population can be defined as the total number of living organisms living together in a particular place and sharing certain characteristics in common.
Generally, these populations may be divided into a fraction of the population (subpopulation) based on certain factors and reasons.
Population regulation can be defined as a biological process that balances limiting factors affecting the growth of a population based on density. The factors that regulate the growth of a population are divided into two (2) main categories and these includes;
I. Density-independent factors.
II. Density-dependent factors.
Density-dependent are regulating factors such as predation, diseases, and competition that affect the size of the population of living organisms through decreasing or increasing mortality and birth rate.
Furthermore, density-independent factors do not have an increasingly greater effect as a population's density increases. Thus, its effect are reduced as a population's density increases in size.
Carrying capacity is the maximum population size that a particular environment can support. The carrying capacity of an environment is denoted by the letter k.

A dominant gene that codes for white hair is represented by the symbol W. If a parent with the genotype WW is crossed with a parent of genotype Ww, what percent of their offspring will have white hair?
A. 25%
B. 50%
C. 75%
D. 100%
Answer:
D
Explanation:
Seeing as the gene is dominate, the hair would still be white evening it's Ww. For the hair to be a different color both parent would need a recessive gene (w), though neither does, meaning all the kids would have white hair.

identify two other physical factors and explain their effect on the organism living in the lake?
Answer:
The correct answer is - light level and temperature.
Explanation:
The structure and function of lakes are determined by various factors such as temperature, light level, wind turbulence, water flow rate, dissolved oxygen, acidity (pH), salinity, habitat size, hydrology, and water depth. Stratification and water circulations are influenced by temperature and wind turbulence.
Light level is an important abiotic factor in lake ecosystems. Light is an essential part for plants to perform photosynthesis. Light can directly affect how much life you find in a given area depends on the production of energy and food by the aquatic plants by photosynthesis.
Temperature is a similarly important factor for lakes or other aquatic organisms as it is for land animals. each organism is able to survive in specific temperature ranges and their metabolic activity also depends on the specific temperature range.
In genetics, what does a genotype of Hh signify?
Answer:
In genetics, Hh means a heterozygote.
Explanation:
Usually, in genetics, H would be the dominant, and h would be the recessive trait. HH is usually dominant, and hh would be recessive. So, Hh would mean a heterozygote. In a heterozygote, this would mean that the recessive trait is in the genotype, but the dominant trait would still take over. This also means that sometimes, the recessive trait can be shown along with the dominant. This can be possible through co-dominance, and incomplete dominance. Hope this helps!
Answer:
CORRECT (SELECTED)
Heterozygous; one dominant allele and one recessive allele
Explanation:
A heterozygous individual (Hh), also known as a carrier, has a genotype with one dominant allele (H) and one recessive allele (h).

What Is Systolic Blood Pressure?
Answer:
It is the pressure when the heart pushes blood out . The number when pressure is checked written on the top is the systolic pressure of the heart .
Explanation:
Hope it helps you dear :)
Good afternoon !
Answer:
Blood pressure is the pressure of circulating blood against the walls of blood vessels. Most of this pressure results from the heart pumping blood through the circulatory system. When used without qualification, the term "blood pressure" refers to the pressure in the large arteries.
Range:-
What is high blood pressure (hypertension)?
Blood Pressure Levels
Normal systolic: less than 120 mm Hg diastolic: less than 80 mm Hg.
At Risk (prehypertension) systolic: 120–139 mm Hg diastolic: 80–89 mm Hg.
High Blood Pressure (hypertension) systolic: 140 mm Hg or higher diastolic: 90 mm Hg or higher.
Units:-
Blood pressure is measured in units of millimeters of mercury (mmHg). The readings are always given in pairs, with the upper (systolic) value first, followed by the lower (diastolic) value.

Freshwater ecosystems can be grouped as those that are still, those that are flowing, and those that contain salt.
Answer:
true
Explanation:
The Pine Tree shown below is a common gymnosperm. Name three adaptations this tree has that allow it to live on land
A waxy cuticle that covers the outer surface of the plant and prevents drying out through evaporation. The cuticle also partially protects against radiation damage from UV light.
Stomata (singular: stoma) are present in all land plant lineages except liverworts (similar to -but not the same as! – mosses). Stomata are pores or holes which allow for exchange of gasses (such as oxygen and carbon dioxide) between the plant cells and the environment. Stomata or similar structures are necessary in land plants because the waxy cuticle blocks free-flow of gasses.
Roots (or root-like structures) anchor plants to the soil and—in plants with true roots— serve as conduits for water absorption. All land plants except Bryophytes (mosses, liverworts, and hornworts) have true roots. Bryophytes have root-like structures called rhizoids that anchor them to their substrate but are not involved in water absorption (which is less important for Bryophytes because they can only survive in very moist environments).
Mutualistic association with mycorrhizal fungi, which are tightly associated with plant roots. Mychorrhizal fungi are associated with approximately 80% of all land plant species and provide additional surface area for absorption of both water and nutrients from the soil. The fungi share these resources with the plant roots, and—in exchange— the plant shares photosynthetic sugar products with the fungi.
The alternation of generations life cycle, which includes both a multicellular haploid stage and a multicellular diploid stage. Why is this an adaptation to life on land? It isn’t, in and of itself—in fact, it also occurs in *some* green algae, which are aquatic but share a common ancestor with all land plants. But specific adaptations to the alternation of generations life cycle have occurred in different lineages of plants, and those adaptations DO function as adaptations to life on land. We’ll consider these adaptations later in this reading.
These are from my text book, from last year.
Answer:
It has cuticle, a waxy, airtight seal that covers plants and allows them to retain water.
It has seeds, plant embryos without a protective cover on the scales of a cone which allows them to disperse into new locations.
It has pollen, but it is not produced in flowers, which allows it to reproduce without the need of water.

A researcher is curious if Bt resistant bollworms are susceptible to an insecticide called DDT. Bollworms susceptible to Bt have genotype RR or Rr, whereas those resistant to Bt have genotype rr. Bollworms susceptible to DDT have genotype tt, whereas bollworms resistant to DDT have genotypes Tt or TT. In an effort to better understand how these two genes are inherited, the researcher crosses an RR tt bollworm with an rr TT bollworm to produce the F1 generation. Then, the researcher crosses the F1 generation to produce an F2 generation. What proportion of the F2 generation is resistant to both Bt and DDT
Answer:
The correct answer is - 3/16 or 18.75% portion will be resistant to both Bt and DDT.
Explanation:
It is given that bollworms that are susceptible to Bt are represented by either RR or Rr and resistance one are shown by rr genotype and bollworms that are resistant to DDT are represent TT or Tt genotype and susceptible to DDT have tt genotype.
Cross: RR tt with rr TT
Gametes: Rt and rT
F1 cross:
RT
rT RrTt ( susceptible Bt and resistant DDT)
F1 Cross with F1
Gametes: RT, Rt, rT and rt
cross:
RT Rt rT rt
RT RRTT RRTt RrTT RrTt
Rt RRTt RRtt RrTt RrTt
rT RrTT RrTt rrTt rrTt
rt RrTt Rrtt rrTt rrtt
The bold genotypes are the three out of 16 that are resistant to both DDT and Bt.
