Answer:
they swap alleles
Explanation:
when homologous chromosomes cross over during meiosis, they exchange segments of DNA/swap alleles. this means that the chromosomes now have a completely unique combination of alleles, which causes variation. It is also random which of these unique chromosomes end up in which daughter cell (the gametes) and since fertilisation is a random and independent event, which unique male gamete that fertilises which unique female gamete is also random. This means the resultant zygote has a unique combination of alleles that is unlike either of their parents.

Answer:
The embryo begins to develop further and at some point, will become a fetus (an organism that is able to survive without needing the mother.)
Explanation:
Before the first trimester, the embryo is not a living, breathing organism and doesn't have a biological sex yet. It cannot survive on its own, so it is therefore part of the mother.
Cows have an incredible digestive system which is highly evolved to process grass in unique ways. Please research and write a short essay regarding the function of the 4 bovine stomachs and how they all work together to process complex carbohydrates. Be sure to include the function of the reticulum, rumen, omasum, and abomasum.
Answer: Ruminants have complex digestive system.
Explanation:
Rumen: It is a sac like structure and first region of the stomach of the cow. It is connected with the esophagus. It forms the storage of the food and convert the food in the form of ball called cud.
Reticulum: It is a honeycomb like structure. It is attached with rumen. It holds and stores the heavy and dense components of the food.
Omasum: It lined with folds of tissues. It absorbs water and nutrients form the food.
Abomasum: It is called true stomach as it operate similar to non-ruminant animals. It secretes hydrochloric acid and enzymes to break down and help in feeding food.

An ATP molecule is made up of 1 ribose molecule, 1 adenine molecule, and 3 phosphate groups joined.
What does the prefix tri- in phosphate mean
Answer:
Tri means three.
Explanation:
The prefix tri means three phosphate molecules are present in in molecule of ATP. ATP molecule is used by the living organisms for performing different activities such as movement, running and breathing etc. When the energy is needed the break down of ATP occurs in which ATP is converted into ADP and phosphate ion, this phosphate ion is used as energy whereas when there is food available this ADP is again converted into ATP.

How are fossil fuels taken from earth?
Answer:Extracting fossil fuels. There are two main methods for removing fossil fuels from the ground: mining and drilling. Mining is used to extract solid fossil fuels, such as coal, by digging, scraping, or otherwise exposing buried resources.
Explanation:
What do consumers gain from
producers because of
photosynthesis?
Answer:
In summary, producers are organisms that make their own food. Producers create food for themselves and also provide energy for the rest of the ecosystem. Consumers are organisms that need to eat to obtain energy. Primary consumers, such as deer and rabbits, eat only producers.

Spring tides are the largest tides due to the combined influence of the Sun and the Moon.
The sunspot cycle results in ice ages on Earth.
Solar flares disturb some radio communications here on Earth.
Geomagnetic storms on the Sun can damage to Earth-orbiting satellites.

how much will atmospheric carbon change in 10 years
Answer:
Explanation:
Carbon dioxide is a greenhouse gas: a gas that absorbs and radiates heat. Warmed by sunlight, Earth’s land and ocean surfaces continuously radiate thermal infrared energy (heat). Unlike oxygen or nitrogen (which make up most of our atmosphere), greenhouse gases absorb that heat and release it gradually over time, like bricks in a fireplace after the fire goes out. Without this natural greenhouse effect, Earth’s average annual temperature would be below freezing instead of close to 60°F. But increases in greenhouse gases have tipped the Earth's energy budget out of balance, trapping additional heat and raising Earth's average temperature.
Carbon dioxide is the most important of Earth’s long-lived greenhouse gases. It absorbs less heat per molecule than the greenhouse gases methane or nitrous oxide, but it’s more abundant and it stays in the atmosphere much longer. And while carbon dioxide is less abundant and less powerful than water vapor on a molecule per molecule basis, it absorbs wavelengths of thermal energy that water vapor does not, which means it adds to the greenhouse effect in a unique way. Increases in atmospheric carbon dioxide are responsible for about two-thirds of the total energy imbalance that is causing Earth's temperature to rise.

of DNA? ACTTACGCCGAT *
(8 Points)
CAGGCATAATCG
ACTTACGCCGAT
TCAATCGCCGTA
TGAATGCGGCTA
Answer:
TGAATGCGGCTA
Explanation:
The complementary DNA codes for A is T and for G its C
Answer:
TGAATGCGGCTA
Explanation:
Remember these are the complementary dna base pairs
adenine with thymine
thymine with adenine
cytosine with guanine
guanine with cytosine
so a would change to t
c to g
t to a
etc
after pairing each letter we would end up with

Biotic and abiotic factors interact with each other to form the ecosystem. Abiotic factors are the non-living things whereas biotic factors are the living things.
What are biotic and abiotic factors?
An ecosystem is made up of biotic and abiotic factors which interact with each other. Biotic factors include those organisms or things which are living and belong to a trophic level in a food cycle. The abiotic factors are those which are non-living but affect the survival of the biotic factors of the ecosystem.
Abiotic factors includes clock, water, paper, glass, aluminum, wooden ruler, sand, clouds, corpse, steak, pork chops, salad, bread, pipe, cotton fabric, wool, gold, plastic, grapes, air, etc.

The diagram below shows a model of the movement of two tectonic plates. When the plates collide, one plate often moves below the other plate. The rising magma that can result from this type of plate movement may produce -
fossil layers
volcanic islands
deep- sea sediment
seafloor spreading
Answer:
volcanic islands
Explanation:
As per the diagram given below that shows the model of the plate tectonics and shows the movement of the two plates one plate collides with another and the there moves under due to subduction.
The magma rises and can lead to the formation of volcanic islands. The island is a geologically active part of the plate that rises upwards and is formed by the process of sedimentation.Hence the option B is correct.

(b) The body cannot supply enough blood to both the digestive system and muscles. (d) the arteries to the leg are open wide.
Explanation:
You shouldn't exercise right after eating a large meal, as you may feel bloating or muscle cramping. It's better to eat low-fiber, low-fat, and high-carbohydrate snacks 30 to 45 minutes before exercising. This can include yogurt, fruit, granola, peanut butter, or whole-wheat toast.

Most populations do not experience: ____ va) exponential growth b) Linear growth c) Resources d) Competition
Answer:
Most populations do not experience: a) exponential growth
Explanation:
Populations that experience exponential growth models show an increase in proportion to their size. The increase in the population size depends on the individual´s reproduction rate: a population that grows at constant exponential rate gains individuals faster as the population increases in size.
This model states that populations live in an environment with unlimited resource availability, so the density factor does not influence population growth. There is no density-dependence effect nor competition for resources. Natality and mortality rate do not depend on density. There is a constant growth rate per capita, and it is proportional to the population size.
Exponential growth is hardly seen in nature due to its characteristics.
Almost every environment shows a carrying capacity point. Carrying capacity is the capability of the environment to support a population. Commonly environments have limited resources and space, and as the population grows, competition increases too. The per capita growth rate decreases as population size increases. Finally, the population reaches the maximum point of carrying capacity, delimited by available resources, such as food or space.
The carrying capacity might be affected by limiting factors, which might be a result of the population density (for example, competition) or might be density-independent. This last case refers to dense-independent factors, and among these, we can mention human impact or natural disasters (fires, volcanic eruption, flooding).
Only a few species can experience exponential growth, such as bacterias.
