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.

A semi-permeable membranous sac contains a 4% NaCl, 96% water solution. This sac is placed into a beaker containing a 16% NaCl, 84% water solution. The membrane is permeable to NaCl. Which way will NaCl flow across the membrane (into or out of the sac)?
Answer:
Should be going out of the sac because the molecules has to balance the concentration not sure tho
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).
What characteristic of water helps in regulating cell temperature and maintaining homeostasis?
Someone please help i need a claim, evidence, then a reasoning !
Answer:
The characteristic of water that helps regulate the temperature of the cells and maintain homeostasis is specific heat (Claim).
Explanation:
Specific heat is a physical property that is defined as the amount of heat needed to raise one gram of a substance by one degree Celsius. In the case of water, its specific heat is higher than that of other substances, being its value 4.186 joules/gram °C, or also 1 calorie/gram °C.
- Claim: The property of water that allows cells to regulate temperature and maintain homeostasis is specific heat.
- Evidence: a high specific heat value of water means that in bodies that possess this molecule in large quantities it is more difficult to raise the temperature
- Reasoning: Living beings are formed mostly by a high percentage of water, much of it in the intracellular compartment. The specific high heat of the water makes it difficult to have sudden changes in the internal temperature, even when the environmental temperature is high, which is a property of water that allows thermoregulation and maintains the balance or homeostasis.
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.
So, B is the correct answer.
Some chemical reactions can produce spectacular displays of energy. In
chemical reactions, some chemical bonds are broken, and some bonds are
formed. Choose the statement that best reflects how energy is involved with
chemical bonds.
A.
B.
C.
D.
Energy is needed to break bonds.
Energy is released when bonds are broken.
Energy is formed in the breaking of bonds.
Energy plays no role in chemical bonds.
Vhich statement do you agree with? Explain your thinking.
Answer: energy is need to break bonds
Explanation:
Compounds form and are stable when they have less energy than the free atoms. Bond energy (in covalent compounds) describes the strength of a bond. The higher the energy holding the atoms together, the more is required to break the bond.
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.

the gene for a particular trait that is passed only from fathers to sons is most likely...
a. autosomal recessive
b. autosomal dominant
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.
