Choose the statement about renewable and nonrenewable energy sources that is NOT true.
a. Renewable energy creates little or no waste and has few negative environmental impacts.
b. There has been little to no recent growth in renewable energy use due to a lack of environmental concerns with the use of fossil fuels.
c. Most nonrenewable energy sources can be renewed, but it takes thousands to millions of years for them to form.
d. New technologies promise future increases in the use of renewable energy sources.
Answer:
b. There has been little to no recent growth in renewable energy use due to a lack of environmental concerns with the use of fossil fuels.
Explanation:
Fossil fuels have had tremendous negative impacts on the environment and humans as well. For that reason, the use of renewable sources of energy, such as hydropower and biomass, have become increasingly popular over the last few decades.
Within our lives, or possibly within many, many lifetimes, the sources of non-renewable energy will run out or cease to exist. The three main fossil fuels that are used as non-renewable energy sources are coal, oil, and natural gas. Carbon is the main element in fossil fuels. Thus, option B is correct.
What best define about nonrenewable energy sources?Fossil fuels have had a terrible impact on both the environment and people. Because of this, the usage of renewable energy sources, such as biomass and hydropower, has risen in popularity over the past few decades.
A natural resource is classified as non-renewable (also known as finite) if it cannot be easily replenished by natural processes at a rate fast enough to keep up with use. Carbon-based fossil fuels are one illustration. The original biological substance can change into a fuel like gas or oil thanks to heat and pressure.
Therefore, There has been little to no recent growth in renewable energy use due to a lack of environmental concerns with the use of fossil fuels.

Changes in the genetic code of a human can be transmitted to offsprings if they occur in what?
If a mutation occurs in a germ-line cell or in simple words that one thing that will give rise to gametes, like egg or sperm cells, then this mutation can be passed to an organism's offspring.
the chromosomal hereditary material is packaged in this organelle in eukaryotic cells but not in prokaryoitc cells. This organelle is called
Answer:
Nucleus
Explanation:
The correct answer would be the nucleus.
The nucleus is a double membrane organelle that is found in all eukaryotic cells but not in prokaryotic cells. It contains the chromosomal hereditary material of eukaryotic cells and serves as the control center of the cell where other cellular activities are dictated.
The chromosomal hereditary materials of prokaryotic cells lie freely within the cytoplasm unlike what is obtainable in eukaryotic cells. The materials are package in a condensed fashion within the eukaryotic nucleus to form a structure known as chromatin. During cell division, the chromatin decondenses and become visible under the microscope as chromosomes.

For Labrador retrievers, black fur is dominant to yellow. a) Explain how two black dogs can have different genotypes. b) Could a black dog have the same genotype as a yellow dog
Answer:
Please find the answers explained below
Explanation:
A) This question involves a Gene coding for fur color in Labrador retrievers (a dog). The allele for black fur (B) is dominant over the alllele for yellow fur (b). Based on the law of dominance by Gregor Mendel, the dominant allele will always mask the phenotypic expression of the recessive allele in a heterozygous state. The two fur colors have different alleles, however, when they come together to form a heterozygote, the black fur is still expressed. Naturally, a black furred Labrador retriever should have the genotype; BB but since the black fur is a dominant trait, another heterozygous genotype will arise as Bb.
B) No, the black dog cannot have the same genotype as yellow dog. This is because the black dog must always have at least one dominant allele (B) in order to be black while the yellow dog, due to the recessiveness of the yellow allele can only have the genotype; bb. Hence, a black dog can either be Bb or BB but a yellow dog can only be bb.

What happens to a population when immigration increases?
A. The population size usually increases.
B. The emigration rate usually increases.
O C. The emigration rate usually decreases.
O D. The population size usually decreases.
Answer:d
Explanation:
When immigration increases, the population size usually increases, as shown in Option A, as immigration is the movement of individuals into a population from another population.
What is immigration?Immigration is the movement of individuals from one population to another. It involves the addition of new individuals to the population, which can increase its size. When more individuals enter a population, they bring with them new genes and genetic diversity, which can enhance the adaptive potential of the population. This can help the population better withstand environmental challenges and increase their chances of survival, but increased immigration can also have negative consequences. For example, it can lead to competition for resources among individuals, which can lead to a decrease in the quality and availability of resources for the population as a whole.
Hence, when immigration increases, the population size usually increases, as shown in Option A.

Common dolphins, whales and other marine mammals are known to undergo apneustic breathing. This breathing process is characterized by periodic or several breathe inhalation, followed by holding their breath and then exhaling them.
Marine mammals can afterwards, went on to dive. This process prevent high water loss out. Thus, they make fewer respirations while maximizing the amount of oxygen produced for optimal consumption.

Snake venom contains a mixture of enzymes, which include phospholipase that break down cell membranes, proteinases that destroy proteins, as well as amino acid oxidases and nucleotidases that break down the monomers for protein and DNA synthesis, which is why they can be so deadly. If you were bitten by a venomous snake you may be treated with an antivenom. In addition to antibodies that help your immune system recognize and fight the foreign molecules, what else does the antivenom most likely contain
Answer:
The correct answer is - Venom enzyme inhibitors.
Explanation:
The snake venoms are the complex mixtures of phospholipase A2s, disintegrins, serine proteases, C-lectins, and metalloproteases, and others. The snake venom phospholipase A2s (svPLA2s) enzymes found in most of the families of venomous snakes that cause anticoagulant effects, cardiotoxicity, neurotoxicity, and cytotoxicity, and other effects.
In antivenom, there are Venom enzyme inhibitors other than antibodies that help in neutralizing these enzymes by weakening or inhibiting these toxic actions.

The RNA product of the genetic code above has the sequence ____________ . It binds to the small subunit of the ____________ . It is joined by the large subunit, completing the initiation stage of the process of ____________ .
The Genetic code was not given, however, The genetic code associated with this question is as follows:
ACCGCTTGCCGCAAT
Answer:
The correct answer is - UGGCGAACGGCGUUA, ribosome, translation.
Explanation:
The translation is the second process of protein synthesis followed by transcription. Transcription produces mRNA sequence from DNA gene sequence and bring it to the cytoplasm for translation to take place.
The gene segment ACCGCTTGCCGCAAT is encoded to mRNA sequence by converting bases to their complementary bases A to U and C to G and G to C and T to A so the new code will be - UGGACGAACGGUGUUA.
This mRNA binds with a small subunit of ribosomes and then a large subunit of ribosome joined and completes the first stage initiation of the translation.

Explanation:
The digestive system consists of the digestive tract and liver. The digestive tract is made up of a large number of parts. These parts include the esophagus, stomach, intestines, rectum, etc. Food enters the mouth and travels down the digestive tract and out passing the rectum. The liver is where the blood passes through and it is responsible for many functions such as the metabolizing of fats and proteins, separating and storing vitamins and minerals, regulating different chemicals found in the blood, etc.
