Answer:
Explanation:
A seed is a plant embryo wrapped in a protective covering. A fruit is the ripened ovary of a plant which contains one or more seeds.
Most plants are rooted in place, which makes dispersing their fruits and seeds particularly important. Seeds that are spread far from the parent plant avoid competition with their relatives for resources and have the opportunity to colonize new areas. Both fruits and seeds have a variety of adaptations for different types of dispersal.
Examples of the some common types of dispersal follow.
Wind
<-- Left : These seeds are transported by air currents. Small fruit or seeds with fine fluff can be carried high up into the air. Herbaceous plants of open areas (like dandelions, cattails, and milkweeds) often have this adaptation. Their seeds float up over neighboring plants even if the parent is growing low to the ground.
Right -->: The fruit of maple trees are also adapted to catch the wind. Many trees (like ashes and sweetgums) have winged fruits or seeds which drop from the tree and are caught by the wind as they fall.
Water
<-- Left : Sea bean seeds are adapted for dispersal by ocean currents. Sea bean vines grow along rivers and coasts. When the pods ripen, they split open and the seeds drop into the water. The beans have a thick seed coat to keep the salt-water out, and have internal structures which make them buoyant enough to float. They can drift for hundreds of miles before washing up onto land.
Coconuts (which are single-seeded fruits) are also adapted for water dispersal. Like sea beans, they have a thick shell to prevent the salt-water from damaging the seed, and the buoyant hull keeps the nut floating.
Animals: internal transport
<-- Left : Brightly colored fruits advertise for dispersers. They are highly visible to birds, promising a nutritious (and often sugary) reward. The seeds are tough and usually undamaged when eaten. They are dispersed when the bird makes a rest stop.
Right -->: Immature seeds in unripe fruit would die if eaten. The green of young fruit hides them among leaves. Unripe fruit are sour or bitter to discourage animals that do find them. Green fruit cling tightly to the plant, making it hard for animals to remove them.
Animals: external transport
<-- Left: Cockle burrs are dry fruit adapted for animal dispersal. The hooked spines catch on the hair (or socks) of passing animals. Dispersal is complete when the animal picks off the offending burr, hopefully dropping it in a new location suitable for growth.
Right -->: Fruit of the unicorn plant have an unusual adaptation for transport. As grazing deer or antelope walk over them, the spines catch around the animals' feet. When the animal finally gets annoyed and shakes the fruit off, dispersal is complete.

B. Genetic engineering is the process of DNA forming into proteins.
C. Genetic engineering is a new practice that doctors can use to help just about any health issue.
D. Genetic engineering is the creation of a new species through artificial DNA.
Answer:
A. Genetic engineering is the manipulation of DNA to produce new organisms or molecules.
Explanation:
Genetic engineering is the process of using recombinant DNA (rDNA) technology to alter the genetic makeup of an organism. ... Genetic engineering involves the direct manipulation of one or more genes. Most often, a gene from another species is added to an organism's genome to give it a desired phenotype.
The Earth’s atmosphere consists of a combination of gases. Scientists believe that we are creating air pollution, which causes an increase in some gases, such as carbon dioxide. Such increases make it difficult for the atmosphere to stay in balance, and heat radiating from the Earth is being trapped. What term refers to the sun’s energy being trapped in our atmosphere?
A) cumulus clouds
B) greenhouse effect
C) transpiration
D) convection
And I need an explanation
Answer:im guessing its the greenhouse effect
Explanation:The Earth's atmosphere is composed of Nitrogen (78%), Oxygen (21%), and other gases (1%). ... Due to increases in gases, like carbon dioxide, that trap heat being radiated from the Earth, scientists believe that the atmosphere is having trouble staying in balance creating the greenhouse effect

B. Four siblings' cells are identical to their parents' cells.
O
C. Four bacteria daughter cells are similar to their parent cell.
OD. Four bacteria daughter cells are identical to their parent cell.
Answer:
A. Four siblings' cells are similar to their parents' cells.
Explanation:
Genetics of offspring are based on the paten but it will never be identical to them. The reason why is when the male and female cells combine to form a child they mix and most of the time one will dominate the other. You can have cases where you have both alleles though. Sometimes they also mix to form a new one. But usually you'll get one from each parent.

Think of another science topic you studied earlier. How might considering scale be useful when investigating that topic? How is that similar to and different from how the crosscutting concept of Scale is useful in this unit?
Scale can be extremely important to consider when applying the conclusions of an investigation to a larger group.
Scale is defined as a series of measurements in a given ratio, in order to compare two objects or groups. Some examples include:
Scale modelsScale populationsIn the case of scale models, one example may be creating a 1:100 scale model of a building. What this means is that the model created will be one hundred times smaller than the original.
The idea of scale is very important to consider when performing experiments. For example, if we were to take a sample of 10 people and test for a specific bacteria, which gives us a result of 1 in 10 (or 10%) of the people that test positive for the bacteria, it would seem as though it is a very small number of people. However, if we take scale into consideration we can apply this 10% to the global population, which will result in hundreds of millions of people who will test positive for the bacteria.
Scale is important to consider when performing any experiment or drawing conclusions because it offers a method to calculate and make an educated assumption as to the impact of the results on a population that would otherwise be impossible to test.

What is the greenhouse effect?
Explanation:
The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the atmosphere and the surface of the Earth.
