What would happen to
offspring if crossing over did
not occur?
Answer: If crossing over did not occur during meiosis, there would be less genetic variation within a species. ... Also the species could die out due to disease and any immunity gained will die with the individual. Two types of gametes are possible when following genes on the same chromosomes. If crossing over does not occur, the products are parental gametes. If crossing over occurs, the products are recombinant gametes.

Explanation:
Answer:
Explanation:
Darwin's Theory of Evolution by Natural Selection
More individuals are produced each generation that can survive. Phenotypic variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive.Charles Darwin's theory of evolution states that evolution happens by natural selection. Individuals in a species show variation in physical characteristics. ... As a consequence those individuals most suited to their environment survive and, given enough time, the species will gradually evolve.

1.animalia
2.plantae
3.fungi
4.protista

1.epiphyllous stamens
2.staminode
Answer:
1. Epiphyllous is anything that is growing on the surface of the leaf or get attached to it of any other plant. ... In this, the stamen gets attached to the part of the flower of some other plant as an adhesion of stamen. Explanation: In other words, Epiphyllous stamen are the Filaments fused with tepals.
2. In botany, a staminode is an often rudimentary, sterile or abortive stamen, which means that it does not produce pollen. Staminodes are frequently inconspicuous and stamen-like, usually occurring at the inner whorl of the flower, but are also sometimes long enough to protrude from the corolla.

How do gravity and inertia work together in our solar system?
Answer:
They work together to keep things in orbit.
Explanation:
Gravity pulls things in, while inertia says that all celestial objects will try their best to continue forward. The results in the orbiting of celestial objects, like the Earth, around other celestial objects, like the Sun.
Answer:
The gravity of the sun and the planets works together with the inertia to create the orbits and keep them consistent. The gravity pulls the sun and the planets together, while keeping them apart. The inertia provides the tendency to maintain speed and keep moving.(Source: sciencing.com)

Many scientists believe that stem cell research will one day lead to new treatments for diseases, but some people have ethical concerns about this research.
Which of the following characteristics of stem cell research is the most likely source of ethical controversy?
A. Stem cells naturally produce many different cell types.
B. Stem cell research requires specialized equipment.
C. Stem cells can replace damaged cells with healthy cells.
D. Stem cells are often extracted from human embryos.
Answer:
D. Stem cells are often extracted from human embryos.
Explanation:
This is a major point of ethical concern and is also a root for many abortion conspiracy theories. The reason it is an ethical concern is because harvesting stem cells often times kills the embryo.
What is the sediment deposited by surface water?
Answer: Delta
Explanation:
A delta is the sediment deposited by the surface water. When the river flows it carries the sediments from the bedrock and also from the surface of the top layer of the soil. These sediments are deposited on a fan like formation that is called as delta. It leads to the development of a landform. It is the most fertile landform as the sediments are rich in mineral content that promote the growth of the plants. This develops when river enters into the ocean, estuary, reservoir, lakes, and any other water body supplying the sediments on the surface.
