C. Using high-density housing to conserve resources
D. Reducing fossil fuel consumption and its associated pollution

Answers

Answer:

The answer is C

Explanation:

Just did it

The sustainable building practice does the photograph show is to using high-density housing to conserve resources. Therefore, option (C) is correct.

The act of caring for these resources so that all living things can benefit from them now and in the future is known as conservation. Natural resources are the source of everything we require for survival, including food, water, air, and shelter.

Recycling the resource allows us to conserve it. For instance, many items can be recycled and repurposed into new ones. Recyclable materials include paper, plastic, glass, metal, and even electronic goods.

identify two other physical factors and explain their effect on the organism living in the lake?

Answers

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.

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

Answers

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       RRTT   RRTt   RrTT    RrTt

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

Answers

Used by people is the answer. :-)

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.

A pair of identical twins develop leukemias, where immature white blood cells proliferate uncontrollably. In each case, the cancer cells analyzed from identical twins displayed an identical chromosomal mutation and this critical mutation was not found in the twins normal cells. The twins developed leukemia at different times in their lives. What is the best explanation for the origin of this chromosomal mutation

Answers

Answer:

The chromosomal rearrangement resulted from a rare somatic mutational event that occurred in utero

Explanation:

Leukemia is a progressive type of cancer where immature white blood cells (leukocytes) proliferate uncontrollably. Next-generation sequencing (NGS) technologies have shown that somatic mutations are relatively common in different types of leukemia such as, for example, acute myeloid leukemia (AML). Moreover, identical twins are developed from one fertilized egg (ovum) that splits and develops into two identical individuals that share all of their genes (i.e., they have exactly the same genetic information). In this case, it is expected that leukemogenesis was initiated in the utero by the occurrence of a chromosomal rearrangement and proceeded early during development as distinct clonalities. In addition, the fact that identical twins developed leukemia at different times in their lives also indicates that this malignancy wasn't caused by only one mutation, but instead it was triggered by multiple mutational events (i.e., leukemia is a multistep cancer caused by secondary genetic changes).

O DNA codes for proteins. Proteins are made up of amino acids.
O Amino acids code for DNA. DNA is made up of protein.
O DNA codes for amino acids Amino acids are made up of proteins.
O Amino acids code for protein. Protein is made up of DNA.

Answers

Answer:

Explanation:

The major relationship between protein and nucleic acid is the reproduction of DNA which contains the information on how cells are used together with RNA which helps to make protein. Both nucleic acid and protein they have four biomolecules which are common in both of them.

Short answer: Using a binary code, genes (DNA) specify how proteins (among other things) are to be synthesized.

Analogy: If DNA is a cooking book, genes are recipes, and proteins the dishes resulting from processing the recipe ingredients.

The relationship between protein, amino acids, and DNA is defined by the DNA codes for proteins. Proteins are made up of amino acids.As DNA codes for proteins.

DNA, RNA, and protein are all intently related. DNA carries the records vital for encoding proteins, even though it does now no longer produce proteins directly. RNA includes the records from the DNA and transforms that records into proteins that carry out maximum cell functions.

The essential process of DNA is to make the proteins that residing matters want to grow.

This is because gene variations can cause an organism to develop new or different traits. Such variations come about either by sexual reproduction (and the mixing of two parents' genes) or by mutation.Mutations, remember, are rare and random changes in one of an organism's genes. Normally, there may be only one mutation in a thousand, or even a million, cell divisions. But with millions of cells in a complex organism or millions of similar one-celled organisms in a particular environment, such accidental changes are always possible.
