(b) growth, (c) metabolism, (d) responsiveness, (e) all of these.
Answer:
The correct option is E..all of these
Explanation:
This is because all living exhibit functional characteristics which are movement, respiration, nutrition, irritability, growth, excretion, respiration and death. This characteristics are indication that organisms are living things.
Growth: it is the increase in size of organisms. All living organisms grow, they increase in size , from zygote to adulthood.
Metabolism...all living organisms excreate, they absorb nutrients and remove unwanted waste products and undigested good like sweat, urine e.t.c.
Responsiveness....All living organisms respond to stimulus, they respond to external environment or change.
In the wild, the plant Knoxiensus prairieii displays a dimorphic trait for fruit color. The plants will bear either purple or yellow fruits. You find and collect several wild plants from around campus and decide to perform some experiments to determine the relationship between the purple and yellow gene traits. You either perform self-crosses (selfing) or you carefully perform cross-pollination experiments between two plants and obtain the following results:
Pollination Purple Progeny Yellow Progeny
Purple (self) 87 0
Purple (self) 76 24
Yellow (self) 0 95
Purple x Yellow 98 0
Purple x Yellow 52 56
Purple x Yellow 85 0
Purple x Purple 91 0
Required:
From these results, explain the mode of inheritance for the fruit color phenotype.
Answer:
The mode of inheritance for the fruit color phenotype is autosomal dominant. Purple color dominates over yellow color.
Explanation:
You will find the complete explanation in the attached files due to technical problems.
Bloom syndrome is an autosomal recessive disease that exhibits haploinsufficiency. A recent survey showed that people heterozygous for mutations at the BLM locus are at increased risk of colon cancer. Suppose you are a genetic counselor. A young woman is referred to you whose mother has Bloom syndrome; the young woman's father has no family history of Bloom syndrome. The young woman asks whether she is likely to experience any other health problems associated with her family history of Bloom syndrome. What advice would you give her?
Answer:
The correct answer is - she is heterozygous for a mutated BLM allele and will have an increased risk of colon cancer.
Explanation:
Autosomal recessive disease expresses itself in next-generation only if there is both alleles are recessive for the gene. In haploinsufficiency, the dominant allele fails to express itself in the phenotype due to insufficiency. So, if even one allele of the recessive gene present in the haploinsufficiency case, it will affect and express its trait.
She is heterozygous for a blood syndrome, as her mother had but her father has no disease, allele and will have an increased risk of colon cancer.
Some cells, such as human nerve and muscle cells contain many more mitochondria than do cells such as skin cells why do some cells have more mitochondria than others
A. The cells use more energy
B. The cells store more nutrients
C. The cells degrade more protein
D. The cells divide more frequently
Answer:
A
Explanation:
different types of cells use different amounts of energy
Some cells, such as human nerve and muscle cells contain many more mitochondria than do cells such as skin cells, some cells have more mitochondria than others as they use more energy. Thus option A is correct.
What are the characteristic feature of mitochondria ?
Mitochondria is commonly called as the “Powerhouse of the cell, these are double membrane-bound organelle present in most eukaryotic organisms located in cytoplasm and function as cell's “digestive system.”
They involve in break down of nutrients and generate energy-rich molecules, cellular respiration occur within the mitochondria, was first described by a German pathologist named Richard Altmann in the year 1890.
The mitochondrion is rod-shaped structure found in both plant and animal cell, size ranges from 0.5 to 1.0 micrometre in diameter, consist outer membrane, an inner membrane, and a gel-like matrix.
The outer and inner membrane are composed of proteins and phospholipid layers which is separated by the intermembrane space.

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.

What did scientists believe was contributing to the depletion of the ozone layer and why?
CFCs and other halogen-source chemicals in the stratosphere were discovered to deplete the ozone layer.
What is ozone layer depletion?
Ozone depletion is the steady lowering of the Earth's ozone layer in the high atmosphere, which is produced by the discharge of chemical compounds from industry and other human activities that contain gaseous chlorine or bromine.
The ozone layer acts as a buffer against the sun's potentially dangerous ultraviolet rays. The destruction of the ozone layer puts humans in direct contact with dangerous ultraviolet rays, which can lead to a variety of health problems including cancer, cataracts, skin illnesses, and a weakened immune system.

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.

If the endoplasmic reticulum were removed from the cell, which organelle would not be able to function properly, and why? mitochondria, because they rely on the ER as an energy source ribosomes, because they receive proteins made by the ER Golgi apparatus, because it packages proteins received from the ER cytoplasm, because it relies on the ER for structural support
Answer:
Golgi apparatus, because it packages proteins received from the ER
Explanation:
The function of the endoplasmic reticulum is to produce proteins. It can be smooth or rough. The rough endoplasmic reticulum has ribosomes, which make the proteins.
The Golgi apparatus receives proteins from the endoplasmic reticulum and modifies and sorts them. They are then concentrated and packed into vesicles which are released out of the cell membrane.
If the endoplasmic reticulum is removed, proteins cannot be made and the Golgi apparatus would not be able to perform its job.
Hope that helps.
If the endoplasmic reticulum (ER) were removed from the cell, Golgi apparatus would not be able to function properly.
