Why do you think that space exploration was pursued despite the risks
Answer:
Because mankind has never stopped pursuing knowledge. It's the thing we all seek. It's something that may get us killed, but may also bring us exactly what we were looking for. People spend their entire lives looking for knowledge, and with the Cold War going on beating the Russians just made seeking the knowledge we wanted as Americans just that much more sweet.

Which of the following domains include prokaryotic organisms?
A. Archaea only
B. Eukarya only
C. Archaea and Bacteria
D. Bacteria only
C. Archaea and Bacteria
Archaea and Bacteria are categorized into the domains of prokaryotic organisms, hence option C is correct.
What are prokaryotic organisms?There are three domains of the life the Archaea, the Bacteria, and the Eukarya, in which Archaea and Bacteria belong to prokaryotic cells but eukaryotic cells belong to the Eukarya domain.
Prokaryotic organisms include the organism's absence of a nuclear membrane and not having well-defined cell organelle, this includes bacteria. It is a unicellular organism having an asexual mode of reproduction.
The Eukarya domain includes the eucaryotic cells having a true nuclear membrane, this domain includes all the eukaryote plants the human beings.
Therefore, Archaea and Bacteria is the correct option.

Explanation:
Taxonomy is a discipline that deals with the classification of living beings, its basic unit of classification being the species category.
A species includes all the individuals with morphological and functional similarities, which also have the capacity to make crosses among them and have a descendant with the same characteristics, including fertility.

Which statement correctly describes the number of chromosomes in body cells and gametes?
Answer:
its A
Explanation:
Body cells and gametes are both diploid correctly describes the number of chromosomes in body cells and gametes.
What are chromosomes?A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones.
Chromosomes are threadlike structures made of protein and a single molecule of DNA that serve to carry the genomic information from cell to cell. In plants and animals (including humans), chromosomes reside in the nucleus of cells.
One molecule of DNA and one protein make up one chromosome. Chromosomes are different sizes, and proteins called histones allow them to pack up small enough to fit in a nucleus.

Which of the following cells is formed by meiosis?
O A. A fertilized egg
O B. A sperm cell
O C. A heart cell
O D. A bacterial cell
Answer:
B. A sperm cell
Explanation:
Meiosis creates gametes/sex cells, such as the sperm and egg.
So, sperm cells are formed by meiosis.
Meiosis doesn't create fertilized eggs, it instead creates normal egg cells.
Meiosis also doesn't create heart and bacterial cells because those are made in mitosis.

Collect information about the kind of waste produced in your house daily and how it is disposed off
Answer:
The different classes of waste produced in a house can be classified as follow: organic waste, liquid waste, solid waste and recyclable waste
Explanation:
In family homes, it is important to understand which are the types of waste in order to know how to dispose of them properly in an environmentally friendly way. First, liquid waste from the bathroom and kitchen is usually directed to the main sewer line or eliminated by septic tanks that serve as sewage collectors. Second, organic and recyclable waste is biodegradable, thereby this type of waste is usually disposed of in incinerators or landfills. Third, solid non-hazardous waste can be eliminated by compressing with mechanical systems and covered with earth to be finally compacted.

When an organelle stops
functioning properly, which of
the following occurs?
Answer:
B.
Explanation:
When an organelle stops functioning properly, what is most likely to occur is that such organelles would be removed from the cell by lysosomes. the correct option, in this case, would be B.
Lysosomes are small spherical molecules with single membranes. The organelle primarily functions in the digestion of cell macromolecules and dead organelles.
Thus, the content of the lysosome is usually filled with digestive enzymes such as protease, lipase, nuclease, etc.
Lysosomes are protected from their own enzymes because of the membrane surrounding them. The contents are not allowed to spill out.

In homologous recombination in E. coli, the protein that moves along a double-stranded DNA, unwinding the strands ahead of it and degrading them, is:
Answer:
RecBCD enzyme
Explanation:
RecBCD is an enzyme of the E. coli bacterium that initiates recombinational repair from potentially lethal double strand breaks in DNA which may result from ionizing radiation, replication errors, endonuclease, oxidative damage, and a host of other factors. The RecBCD enzyme is both a helicase that unwinds, or separates the strands of DNA, and a nuclease that makes single-stranded nicks in DNA.

How can we explain the observation that traits, such as skin color, are fairly consistent within a racial group, but alleles for skin color are not consistent
Answer:
Skin color is a quantitative trait influenced by the combined action of many genes, thereby different gene pools can result in the same skin color.
Explanation:
Quantitative traits (also known as continuous traits, ) are phenotypic traits that depend on the combined action of many genes and the environment. These traits show continuous variation, changing gradually over a range of values in the population. Examples of quantitative traits include height, skin color, weight, etc. A gene pool is the sum of all the individual genes in a population. In consequence, different populations may show different allele combinations (gene pools) that result in the same phenotype for a quantitative trait (skin color).

c. co-dominant
d. incompletely dominant
e. Y-linked
f. X-linked
Answer:
e. y-linked
Explanation:
Because women have XX chromosomes they will inherit an X from their mom and an X from their dad.
However, men have XY chromosomes so they inherit an X from their mom and a Y from their dad.
If the father had a trait attached to his y chromosome he would not pass it to his daughters, but it would pass on to his sons.
