Answer:
1st law: Law of segregation
Explanation:
Mendel’s First Law: Law of Segregation During each round of meiosis, chromosomes are separated into daughter cells. This means that one half of the genetic material goes to one gamete and the other half goes to the other. Mendel’s first law essentially states that the alleles in one locus segregate into separate gametes.

Answer:
the chlorophyll
Explanation:
A small crab will make its home inside a mussel, obtaining food and shelter while the mussel simply tolerates the situation. In contrast, a different crab falls victim to an intruder who slowly extracts nutrients from its body by spreading a fungus-like substance throughout its extremities.

Earthquakes and faults form at __________ boundaries.
transform
convergent
divergent
Answer:
transform
Explanation:
Most earthquakes occur at the boundaries where the plates meet. In fact, the locations of earthquakes and the kinds of ruptures they produce help scientists define the plate boundaries. There are three types of plate boundaries: spreading zones, transform faults, and subduction zones.

What is the correct mRNA transcription of the following DNA sequence? ATGGCACCTTAC
A. UACCGUGGAAUG
B. AUGGCACCUUAC
C. CAUUCCACGGUA
D. CATTCCACGGTA
The process of transcription produces the mRNA sequence from the DNA. The mRNA transcription of ATGGCACCTTAC will be UACCGUGGAAUG. Thus, option A is correct.
What is mRNA transcription?Transcription is the process of the formation of mRNA from the replicated DNA strand of the cell. It produces an mRNA transcript that is a single strand and further codes for amino acids.
The mRNA transcript forms by the base pairing with the DNA template. If the DNA sequence is ATGGCACCTTAC then according to the base pairing rule the adenine (A) pairs with uracil (U) in mRNA, and guanine (G) pairs with cytosine (C). In mRNA, the adenine binds with uracil and not thymine, and hence A pairs with U, whereas the G-C bond remains the same.
The DNA strand: ATGGCACCTTAC
The mRNA sequence will be: UACCGUGGAAUG
Therefore, option A. UACCGUGGAAUG is the mRNA transcript.

What happens to water (H2O) and carbon dioxide (CO2) during photosynthesis?
Answer:
Carbon dioxide turns into glucose and water turns into oxygen
Explanation:
carbon dioxide is combined wih hydrogen atoms in the presence of ATP molecules to form glucose
water molecules split by sunlight energy to form oxygen gas and hydrogen atoms . the oxygen obtained from water is released by the leaf as a by- product

Answer:Fossil fuels are the largest sources of energy for electricity generation. Natural gas was the largest source—about 38%—of U.S. electricity generation in 2019.Explanation:
Answer:Fossil fuels are the largest sources of energy for electricity generation. Natural gas was the largest source—about 38%—of U.S. electricity generation in 2019.Explanation:The United States uses many different energy sources and technologies to generate electricity. The sources and technologies have changed over time, and some are used more than others. The three major categories of energy for electricity generation are fossil fuels (coal, natural gas, and petroleum), nuclear energy, and renewable energy sources. Most electricity is generated with steam turbines using fossil fuels, nuclear, biomass, geothermal, and solar thermal energy. Other major electricity generation technologies include gas turbines, hydro turbines, wind turbines, and solar photovoltaics.
