How have trees adapted to survive through the cold winter months?
Answer:
Adaption
Explanation:
Adaptations. Deciduous plants handle the lack of water by shedding their leaves, which tend to evaporate water into the air. During cold winter months, most deciduous plants drop their leaves and go dormant. Plants may hold onto dead leaves for insulation, or use deep snow like a blanket to protect against the cold.
Tonya's father does not have the dominant trait of webbed feet, and neither does Tonya's mother. What is the percentage that Tonya or any of
her brothers of sisters will have webbed feet?
Answer:
0%
Explanation:
For Tonya or her siblings to inherit one of their parents must have that allele. Since both her parents have the recessive phenotype that means neither of her parents carry the dominant gene so it would be impossible for Tonya or her siblings to have webbed feet.
how are checkpoints currently behaving in sally cancer cells
Answer:
Instable behavior.
Explanation:
The checkpoints currently behaving instable in sally cancer cells because mutants show genetic instability so this instability is the cause of cancer disease. Two checkpoints are sensitive to DNA damage, one occur before mitosis cell division and the other occur before replication of DNA. So damage occur in these two check points leads to instable behavior of cancer cells.
8. In chickens, brown feathers are dominant over red feathers. Suppose we cross two heterozygous chickens.
Draw the punnett square and list the genotypes and phenotypes of the offspring.
I
Genotypes of offspring:
Phenotypes of offspring:
Plz help me
Answer:
Crossing two chickens heterozygous for the trait feather color, when brown feathers are dominant over red feathers, will produce offspring with brown and red feathers in a brown:red phenotypic ratio of 3:1.
Explanation:
Knowing that in chickens brown feathers are the expression of the dominant allele (B) and the recessive allele is red (b), crossing two heterozygous individuals (Bb) will result in offspring that are likely to have brown or red feathers.
The cross can be represented by a Punnett Square:
Bb X Bb cross
alleles B b
B BB Bb
b Bb bb
Where the result is:
Genotypes:
Bb, 50% BB, 25% bb, 25%Phenotypes:
Brown feathers, 75% Red feathers, 25%.In this case, the probability of having brown or red feathers is 3:1.
How do typical human body temperature and pH explain why lactase can work efficiently in the human body of most humans?
Answer:
Lactase requires 6 pH and 37 degree Celsius temperature.
Explanation:
Lactase can work efficiently in the human body of most humans because the pH and temperature of the body is favorable for the lactase to work. Lactase has a range of pH from 2 to 7 but work best at the pH 6 and at the temperature of 37 degree Celsius which is the human body temperature and pH so that's why the lactase can work efficiently and effectively in the human body.

Short answer: To lower the price of oil and reduce dependence on foreign imports, a federal government is debating whether to open large stretches of its coastline to domestic drilling. Evaluate this plan in terms of two ecosystem services that the country might gain and two services the country might lose if the coastline is opened for drilling. In your answer, be sure to explain how a perceived negative externality might become an internal cost.
Answer:
This drilling enhances economy of the country but at the same time disturbs aquatic animals.
Explanation:
Due to drilling at coastline, oil should be extracted from the sea which fulfills the oil requirement of the country and valuable money can earned by exporting this oil. Due to this drilling, the habitat of aquatic animals are destroyed and no trade should be done from this coastline with other countries because the area is now only for drilling. So this plans has both positive effect on the country's economy but has negative impacts on the environment and ecosystem.

C. Anton van Leeuwenhoek
D. Robert Hooke
E. All of the above helped in developing the cell theory
PLEASE HELP!!
The given statement is false and the cell hypothesis was created by Rudolf Virchow, Theodore Schwann, and Matthias Jakob Schleiden, hence option B is correct.
What is cell theory?As a result, van Leeuwenhoek and Schwann did not independently develop the cell hypothesis.
The scientific idea that cells make up living beings, that they are the fundamental structural and organizational unit of all species, and that they all originate from previously existing cells is known as cell theory.
Typically, three scientists Theodor Schwann, Matthias Jakob Schleiden, and Rudolf Virchow are credited with creating the cell theory.
Therefore, Schwann and Schleiden proposed that cells were the fundamental building block of life in 1839.

Which of the following is true regarding the large intestine?
А
It is the major site of water absorption.
B
It is four times as long as the small intestine.
Most chemical digestion occurs there.
D
It contains salivary glands, which secrete amylase.
The statement that is true regarding LARGE INTESTINE is option A which states that It is the major site of water absorption.
The LARGE INTESTINE is part of the alimentary canal in the digestive system of mammals. The main function of
• Is to absorb water and salts from the material that has not been digested as food, and
• get rid of any waste products left over.
The main parts of the LARGE INTESTINE includes:
• the cecum,
• the colon, and
• the rectum
From the cecum, the undigested food passes into the colon. Here, WATER is ABSORBED. This concentrates the waste products and makes them semi-solid. In this state, the waste products are called faeces. Faeces pass into the rectum and out of the body through the anus.
Therefore the statement that is true regarding LARGE INTESTINE is that It is the major site of water absorption.
