Answer:
B: The male cat is XY, while the female cat is XX, and the Y chromosome is
smaller than the X.
Explanation:
Y chromosomes are smaller than X chromosomes so the mass of DNA is smaller in male cells than female cells
The Y chromosome is smaller than the X chromosome. So, there is less nucleotide in the DNA of a female cat. Hence, option B is correct
What is DNA?DNA stands for deoxyribonucleic acid and it is a polymer of nucleotides. It is double-stranded in structure. It is hereditary material present in the cells of organisms. Nucleotides consist of pentose sugar, nitrogenous bases, and phosphate.
DNA is organized in the nucleus in the form of dense protein complexes known as chromosomes. 38 chromosomes are present in cats. There are two types of chromosomes in cats X and Y. Male cat contains XY chromosomes and female cat contains XX chromosomes. The Y chromosome is shorter than the X chromosome.
Therefore, the normal range of the mass of DNA in a male cat cell is lower than that of a female cat. Hence, option B is correct

If a couple has four daughters the % chance of their next child being a daughter is
Answer:
50% chance
Explanation:
Humans have two sex chromosomes, the X chromosome and the Y chromosome. Males inherit both X and a Y chromosome, while females inherit two X chromosomes. Thus, the sex of the child is determined by the sex chromosome carried by the male gamete (i.e., X or Y chromosome) which fuses with the egg cell (always containing an X chromosome). In consequence, the chance of having a sperm containing an X chromosome (i.e., the chance of having a girl) is an independent event of previous fertilization events (which led to the formation of 4 different female zygotes), thereby the probability will be 50%.

How do matter and energy interact in a food web or energy pyramid model?
Answer: The higher up the pyramid the less energy there is.
Explanation: There is more competition
Answer:
At each link upward in a food web, only a small fraction of the matter consumed at the lower level is transferred upward, to produce growth and release energy in cellular respiration at the higher level. ... At each link in an ecosystem, matter and energy are conserved.
Explanation:
1. In the process of (selective breeding / natural selection/hybridization/
DNA replication), plants or animals with desired traits are mated. By repeating
the process over many generations, useful plant strains or animal breeds are
developed. The process is an example of (bioremediation / natural selection /
biotechnology / feedback inhibition).
Answer:
selective breeding; biotechnology
Explanation:
Selective breeding is a type of artificial selection that consists of crossing plants/animals with desirable and heritable phenotypic traits in order to increase the frequency of such traits in progeny. Selective breeding can be considered as one of the first biotechnological techniques applied by humans. In the past, the selective breeding technique has allowed obtaining domesticated animals (e.g., dogs from wild wolves) and domesticated crops from their wild ancestors (e.g., maize from its wild ancestor teosinte).

A converging lens can be defined as ___
A) a lens that causes parallel light rays to bounce off the surface
B) a lens that causes parallel light rays to separate from each other
C) a lens that allows parallel light rays to pass without changing directions
And D) a lens that causes parallel light rays to focus at a specific location
Answer:
D) a lens that causes parallel light rays to focus at a specific location
Explanation:
Lexically, to CONVERGE means to MEET. Converging lens, also known as double convex lens is that which causes rays of parallel light to become focused at a point i.e meet at a specific location.
The parallel rays of light come from different direction but the converging lens is structurally suited to cause them to converge or focus at a point.

Jonathan consumes five 12 ounce beers throughout the day. How many additional
calories has he added to his diet?
710 kcals
630 kcals
490 kcals
280 kcals
The given options must be in the calories in approximate value.
Answer:
The best answer is - 710 calories approximately.
Explanation:
One ounce of the beer provides 12 calories and as it is given that Jonathan drinks five 12 ounce beers throughout the day then,
12 ounce = 12 × 12 × 5
= 144 × 5
= 720 calories
Thus, it is found out that he has added 710 calories approximately to his diet additional.

What is the structure of DNA?
Humans and nearly all other species carry their genetic information in DNA, also known as deoxyribonucleic acid. The DNA of an individual can be found in almost all of their cells.
Deoxyribonucleic acid (DNA) is made up of the four nucleotides A, C, G, and T. These nucleotides are linked together by a backbone made up of alternating phosphate and deoxyribose sugar residues. The complementary pairs of these nitrogen-containing bases are governed by their capacity to generate hydrogen bonds.
DNA is located inside the nucleus, a specific region of the cell, in eukaryotic species.
Therefore, chromosomes are the name for this DNA that has been packed.

Which has a lower albedo, a black sheet of paper or a white sheet of paper?
Well let's see, the substance with the highest albedo value will absorb less light and will reflect most of the light falling on it. The substance having the lowest albedo will absorb most of the lights falling on it. A black sheet of paper will absorb most of the light falling on it, so this means that a black sheet of paper will have the lower albedo

.When animals breathe, they take in oxygen and give off carbon dioxide. How is photosynthesis like or unlike this process?
Once they have carbon dioxide and water, they can use solar energy to create food. Another gas called oxygen is a by-product of the production of plant nourishment. The leaves emit this oxygen into the atmosphere.
What animals breathe, take in oxygen give carbon dioxide?The act of breathing in oxygen and exhaling carbon dioxide is generally referred to as respiration. The phrase is more precisely used to describe the chemical process that organisms undertake to extract energy from food, a process that normally entails the inhalation of oxygen and exhalation of carbon dioxide.
Therefore, One of the first concepts covered in biology class is that, whereas plants absorb CO2 throughout the day and release oxygen, animals breathe in oxygen and exhale CO2. Plants use the energy from sunlight to transform CO2 and water into sugar and oxygen through a process known as “photosynthesis.”

1. Which of the following is NOT a key factor important to the development of human society?
A. Access to clean water
B. Access to fertile soil
C. Access to cities
D. Access to natural resources
Access to cities is not a key factor important to the development of human society, but clean water, fertile soil, and Access to natural resources all are needed, hence option C is correct.
What are factors important to the development of human society?The preagricultural (hunting and gathering) stage, the agricultural stage, and the industrial stage are thus the at least three primary stages of societal evolution or civilizations.
Clean water is essential to our way of life because it creates a habitat for species and places to fish, paddle, surf, and swim. Our economy is reliant on clean water to operate and thrive. This includes industries like manufacturing, agriculture, tourism, recreation, and energy generation.
They support tax revenue, income, and the fight against poverty. Natural resource-related industries generate employment and frequently form the backbone of poorer towns' economies.
Therefore, natural resources are fundamentally important, so they must be managed responsibly.
