they are identical
they have genes for the same traits
they are in pairs
they have genes that are in the same order
Answer:
Homologous chromosomes are NOT identical.
Explanation:
They contain slight differences in their genetic information, allowing each gamete to have a unique genetic makeup. Consider that the homologous chromosomes of a sexually reproducing organism are originally inherited as two separate sets, one from each parent. Hope this helps :)
Bart believes that mice exposed to microwaves will become extra strong (maybe he's
been reading too much Radioactive Man). He decides to perform this experiment by
placing 10 mice next to a microwave for 10 seconds. He compared these 10 mice to
another 10 mice that had not been exposed. His test consisted of a heavy block of wood
that blocked the mouse food. He found that 8 out of 10 microwaved mice were able to
push the block away. 7 out of 10 of the non-microwaved mice were able to do the same.
What was one of the constants in this experiment?
Answer:
the mice were able to move the block

3. evergreens are plants that maintain their leaves in all seasons and include trees such as Pine, Cedar, and Mango.
Explanation:
Deciduous trees: These plant species lose their leaves every year during the cold and dry autumns and winters, as it is the most limiting period over the year. Foliage resprout again during the warmer wet season when it rains more often, during spring and summer. Template forest biome characterizes for having deciduous trees such as oaks, maple, or elm, among other phanerophyte species.1. deciduous trees lose their leaves seasonally and include trees such as elm and maple.
Conifer: Correspond to the gymnosperm group. They are perennial, vascular, evergreen, woody plants. They characterize for having a straight trunk with secondary growth and no vessels in the xylem tissue. Their branches usually develop horizontally, with needle-like leaves growing on them, unisexual flowers, and seeds included in a cone.
2. conifer leaves are generally thin and needle-like, while seeds are contained in cones. conifers include pine and cedar.
Evergreens: Perennial plants that keep their green leaves the whole year. These are the opposite of the deciduous trees. Tropical forests characterized for having these broadleaf plant species, such as mango, that are favored by the environmental conditions as precipitations are abundant and the average temperature is elevated most of the year. Also, many evergreen plants are typical of the boreal forest. Pines, cypress, cedar, and sequoia are examples of these last ones.
3. evergreens are plants that maintain their leaves in all seasons and include trees such as Pine, Cedar, and Mango.
Hardwoods: Angiosperms. Xylem with vessels. These species present a high diversity in shape, textures, and sizes. They might reproduce asexually or sexually by producing flowers, fruits, and seeds. Also, they might be either evergreen or deciduous.4. hardwoods reproduce using flowers and have broad leaves; hardwoods include trees such as Elm, Maple, and Mango.

Which of the following are true statements about ozone holes? (Select the three best
answers.)
A.Ozone holes don't have any ozone in them.
B. Ozone holes allow ultraviolet light to reach the Earth's surface.
C. Chlorofluorocarbons make an ozone hole larger.
D. Ozone holes have more ozone than usual.
E. Ozone holes can be hole-shaped.
F. There is always just one ozone hole in the Earth's atmosphere.
Answer:
Ozone holes have more ozone than usual.
Correct Answer
Ozone holes allow ultraviolet light to reach the Earth's surface.
Ozone holes don't have any ozone in them.
Chlorofluorocarbons make an ozone hole larger.
Explanation:
Ozone has been the atmospheric layer that protects the earth. It allows the ultraviolet rays to enter the earth, and there is one ozone hole due to the Chlorofluorocarbons. Thus, options B, C, and F are correct.
What is an ozone hole?An ozone layer is defined by the presence of the ozone gas that is present in the atmosphere of the earth. The ozone hole is the hole in the ozone layer that is due to the depletion of the ozone gas in the layer due to increased global warming and pollution.
The increased concentration of Chlorofluorocarbons (CFCs) generated from aerosols, air conditioners, and refrigerants have resulted in a hole in the ozone layer. This lead to increased exposure of the organism to the harmful UV radiations emitted from the sun.
Also, this has resulted in increased climatic changes because of the global warming and heating of the atmosphere due to the entrapment of the UV and Sun rays. This leads to various diseases including cancer and eye irritation.
Therefore, the ozone hole is due to increased Chlorofluorocarbons. options B, C, and F are correct.

How might environmental manipulation of a crop have unexpected consequences? a. The new crop may require more water than the original. b. The crop may harm the environment. c. The yield may be reduced. d. All of the above Please select the best answer from the choices provided
Answer:
D all of the above
Explanation:
just took the test
Environmental manipulation can have both types of consequences - beneficial as well as adverse. At times, these changes can be unexpected too. The correct option is D.
What negative effect does environmental manipulation of a crop have?The crop can have a need for more water as compared to the original if there would be a change in the soil, region or even climate of the crop. An increase in the temperature can affect the availability of water to the crop.
Changes in the soil can result in variation in the availability of minerals required for the growth of plants. This can cause improper health condition of the crop, which will ultimately decrease its yield.
Overuse of fertilizers and pesticides can affect the quality of the soil and also have a negative impact on the crop. It can also be passed on to the consumers of the crop due to bioaccumulation.
Thus, all of the mentioned statements are correct. Hence, the correct option is D.
