Answer:
nucleus and we need dna so we can figure out people in our past
Explanation:
In eukaryotic cells, DNA is present inside the nucleus of the cell. DNA is important because it codes for life processes, and it transfers to the next generations.
What is DNA?Three subunits, nitrogenous bases, hydrogen bonding, and a phosphorus backbone make up the double helix structure of DNA. It is a component of genetic material found in all living things.
Every organism has a unique strand of DNA. Although DNA is composed of the same components as those listed above, the bases are joined in a different order. Every organism's genetic makeup was altered as a result.
DNA is found inside the nucleus of the cell, and in prokaryotes, it is found in a coiled form in the center of the cell.
Therefore, the DNA is found in the cell's nucleus of eukaryotic cells. DNA is significant because it transmits to subsequent generations and codes for biological functions.

A. What kind of weather is associated with a low-pressure area?
B. What happens to the air of the low pressure areas that leads to this type of weather?
Answer:
A.) Low-pressure systems are usually associated with clouds and precipitation that minimize temperature changes throughout the day
B.) The slightly inward moving air in low pressure causes air to converge and since it can’t move downward because of the surface, the air is forced upward, leading to condensation and precipitation

Does human intervention affect small-scale ecosystems differently than large-scale ecosystems?
two pieces of information along with their sources
Answer: No
According to BBC, Human activities such as harvesting plants and hunting animals can unbalance the flows and cycles within those [SMALL SCALE ECOSYSTEMS ]ecosystems. Tree-felling may lead to soil erosion and a loss of habitat. Lack of shade and moisture in the soil can result in desertification.
According to National Geographic, Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.

how will climate change affect the habitat distribution for the baltimore oriole?
Climate change has a great effect on the habitat distribution of Baltimore orioles bird.
Climate change will adversely affected the habitat distribution of Baltimore orioles because climate change causes heat waves, wildfires and intense downpours which is harmful for Baltimore orioles.
The climate changes will limit the populations of ranges of Baltimore oriole as well as changes the habitat. These Baltimore orioles moved to other places where the climate is favourable so we can conclude that climate change has a great effect on the habitat distribution of Baltimore orioles bird.

A possible source of additional salt in the stream is the influence of the ocean upstream.
The map shows the course of the Mississippi River through the states of Minnesota, Wisconsin, Iowa, Illinois, and Missouri and its mouth in the Ocean.
According to this information, the salinity detected in South Dakota of the Mississippi River can be caused by the influence of the salty water of the Ocean against the current of the river.

Explanation:
What is the probability that a couple will have a type A child if the mother has Type
A blood and is heterozygous for the trait and the father has type AB blood?
Answer:
50%
Explanation:
To solve this, we'd need to use a Punnett square. Since the mother has a heterozygous genotype and has an A-blood phenotype, we know that she is AO and the father is AB.
A B
A AA AB
O AO BO
According to this, the four possible blood types, with equal probability are: AA, AB, AO, and BO. Both AA and AO genes will result in type-A blood, since A is dominant over O. Therefore, there is a 2 in 4 (or 1 in 2, or 50%) chance of the child having type-A blood.

In angiosperm double fertilization, one sperm nucleus fertilizes the ______ to form the diploid ______, and a second sperm nucleus fuses with the two nuclei in the central cell of the embryo sac.
Answer:
one sperm fertilizes the egg cell, forming a diploid zygote
Explanation:
Hope it helped
please mark as brainliest
In angiosperm double fertilization, one sperm nucleus fertilizes the egg to form the diploid zygote, and a second sperm nucleus fuses with the two nuclei in the central cell of the embryo sac.
The egg is the female gamete in an angiosperm. It is a haploid cell that contains one set of chromosomes. The zygote is the fertilized egg. It is a diploid cell that contains two sets of chromosomes. The zygote will eventually develop into an embryo. The central cell is a cell in the embryo sac that contains two haploid nuclei.
Double fertilization is a unique feature of angiosperms. It is a type of fertilization in which two sperm nuclei fertilize two different cells in the embryo sac. The first sperm nucleus fertilizes the egg to form the zygote. The second sperm nucleus fuses with the two nuclei in the central cell to form a triploid cell. This triploid cell will eventually develop into the endosperm, which is a food reserve for the developing embryo.

Describe why enzymes are important in all living organisms?
Answer:
Enzymes are important because they make the chemical reactions in cells happen quickly.
Enzymes, by speeding up biological reactions, ensure that all necessary activities in a cell can take place simultaneously and prevent one particular activity from overtaking the entire cell or organism. This is possible because enzymes allow chemicals to react more specifically with only certain substances rather than reacting indiscriminately with any number of different substances within cells.
The most famous example of this enzyme effect is when stomach acid reacts with pepsin that turns food into a liquid. The body then uses this liquid for absorption through the intestines where nutrients are then used throughout the body. It's important for people to have enough enzymes in order to digest their food fully however if
