Asbestosis is a condition that affects the
O A. heart
O B. brain
O C. lungs
D. kidneys
Answer:
lungs
explanation:
Asbestosis (as-bes-TOE-sis) is a chronic lung disease caused by inhaling asbestos fibers. Prolonged exposure to these fibers can cause lung tissue scarring and shortness of breath. Asbestosis symptoms can range from mild to severe, and usually don't appear until many years after continued exposure
Answer:
C.Asbestosis is long term inflammation and scarring of the lungs due to asbestos fibers. Symptoms may include shortness of breath, cough, wheezing, and chest tightness. Complications may include lung cancer, mesothelioma, and pulmonary heart disease. Asbestosis is caused by breathing in asbestos fibers.

I think its D
Explanation:
B. The Sun is farthest south is the sky is true. A is wrong because in the Northern Hemisphere because the northern part of Earth is tilted most toward the sun. C is also wrong because in September and March – when the Sun shines directly on the Equator and the length of day and night is nearly equal not in winter. And D is wrong because South Pole has 24 hours of daylight not darkness.

Pure-breeding pea plants with the dominant long-stem trait were crossed with pure-breeding pea plants with short stems. The F1 generation was allowed to self-pollinate. If the long-stemmed offspring of the F2 generation are test crossed, what fraction of their offspring are expected to have short stems? Select one: a. 3/4 b. 1/2c. 1/3 d. 1/4
Answer:
b
Explanation:
First, let us assume the long-stem trait to be represented by the allele A and its short stem counterpart by the allele a.
Pure-breeding long-stem = AA
Pure-breeding short-stem = aa
AA x aa
F1: Aa Aa Aa Aa
The F1 generation was allowed to self-pollinate
Aa x Aa
F2: AA Aa Aa aa
Test-crossing means crossing an organism of doubtful zygosity with a phenotypically recessive version of the same organism.
From the resulting F2, the long-stemmed offspring are of 2 genotypes - AA and Aa. If AA is test-crossed with a phenotypically recessive version:
AA x aa
Aa Aa Aa Aa
all the offspring are expected to have long stems.
If the Aa offspring is test-crossed with aa:
Aa x aa
Aa Aa aa aa
Half or 1/2 of the offspring are expected to have short stems.
Considering the second cross, the correct option is, therefore, b.

Describe the basic storage mechanism for DNA using the words histone complex, nucleosome, chromatin and chromosome.
Answer:
Chromosomal DNA is packaged inside microscopic nuclei with the help of histones. These are positively-charged proteins that strongly adhere to negatively-charged DNA and form complexes called nucleosomes. ... Nucleosomes fold up to form a 30-nanometer chromatin fiber, which forms loops averaging 300 nanometers in length.
Explanation:
Histones help to package chromosomal DNA inside microscopic nuclei. These are positively charged proteins that bind to negatively charged DNA to form complexes known as nucleosomes.
What are nucleosomes?A nucleosome is made up of about 150 base pairs of DNA rolled up around a core of histone proteins.
The nucleosomes recurrently fold in on themselves to tighten and condense the packaged DNA when forming a chromosome.
Histones help to package chromosomal DNA inside microscopic nuclei. These are positively charged proteins that bind to negatively charged DNA to form complexes known as nucleosomes.
Thus, in this way, DNA gets stored.

How does the burning of fossil fuels and deforestation contribute to the overall amount of carbon dioxide?
Answer:
Forests store large amounts of carbon. When fossil fuels are burned, carbon from dead and decayed plants, animals and phytoplankton that lived hundreds of millions of years ago (before dinosaurs existed), is released into the atmosphere in the form of carbon dioxide. .
types of transpiration
Answer:
Types of Transpiration
There are three different types of transpiration in plants:
Stomatal Transpiration
It is the evaporation of water from the stomata of the plants. Most of the water from the plants is transpired this way. The water near the surface of the leaves changes into vapour and evaporates when the stomata are open.
Lenticular Transpiration
Lenticels are minute openings in the bark of branches and twigs. Evaporation of water from the lenticels of the plants is known as lenticular transpiration.
Lenticels are not present in all the plants. A minimal amount of water is lost through lenticels.
Cuticular Transpiration
It is the evaporation of water from the cuticle of the plants. The cuticle is a waxy covering on the surface of the leaves of the plants. About 5-10% of the water from the leaves is lost through cuticular transpiration. During dry conditions when the stomata are closed, more water is transpired through the cuticles.

Karizma is surprising her mother with her favorite red carnations, but the flower shop only had white. So, Karizma places the white carnations in a solution of water and red food coloring. The carnations turned red by the next day. What could be the possible explanation?
A. Phototropism is responsible for pulling the food coloring from the roots to the petals.
B. The roots pulled up the food coloring with the water and it was transported through the phloem to the petals.
C. Gravity assisted the plant in carrying the food coloring to the petals.
D. Thigmotropism is responsible for pulling the food coloring from the roots to the petals.
E. The roots pulled up the food coloring with the water and it was transported through the xylem to the petals.
Answer:
The roots pulled up the food coloring with the water and it was transported through the xylem to the petals.
Explanation:
the xylem is one of the transport tissues in plants. It transfers water and nutrient from roots to stems and leaves.

The cells found throughout the digestive system all look very similar.
true or false
Answer:
True
Explanation:
In the levels that make up the organization of life, CELLS are the smallest and simplest components of life. According to the hierarchy, cells make tissues, tissues make organs, organs make organ systems, organ systems make organisms. Based on this question, the DIGESTIVE SYSTEM falls under the SYSTEM category of the hierarchy meaning that it comprises of organs performing similar functions that makes it up.
However, these organs as well contain tissues and subsequently cells which makes up the digestive system. Since the cells, tissues, and organs all work together for the process of digestion, it means that the cells found in the digestive system are SIMILAR to one another in appearance.

Based on California’s experience with Caulerpa, the killer algae, explain why it is important to regulate the pet and aquarium trade.
Answer:
Based on California's experience with Caulerpa, the killer algae, explain why it is important to regulate the pet and aquarium trade. Even species that are kept as pets and in aquariums should be regulated and tracked because their accidental release can have serious negative environmental impacts.
Explanation:
Even species that are kept as pets and in aquariums should be regulated and tracked because their accidental release can have serious negative environmental impacts. Some owners and aquarium keepers intentionally release these species into the wild rather than destroy them, and accidental release is always a risk. Therefore, if a potentially destructive species is going to be kept as a pet or in an aquarium they should be regulated so proper safety precautions can be taken.
