Explanation:
A mountain climber climbs to the summit of a 7 km mountain and then returns to his campsite located at the base of the mountain. Explain what happens to the temperature and pressure as he ascends to the summit and returns to his campsite.
Answer:
Temperature reduces and pressure increases as he ascends to the summit while the reverse of this happens when he returns to his campsite
Explanation:
When a person climbs a summit, the pressure increases but the temperature reduces. but as he returns to his campsite the normal temperature and pressure are regained which means the pressure reduces and the temperature increase.
The temperature and pressure decreases as he ascends the mountain and increases as he descends the mountain.
We know that temperature and pressure decreases with altitude. In fact, the temperature decreases by 6.5°C for every 1000 meters increase in altitude. Hence air pressure decreases with increasing altitude.
Hence, for a mountain climber, the temperature and pressure decreases as he ascends the mountain and increases as he descends the mountain.

How does DNA copy itself
Explanation:
DNA unwraps itself before cell division. It helps that each side of the double helix is in opposite direction of the other. Then the DNA polymerase travels around each strand and binds the complementary nucleotides (DNA's building blocks). The process is called DNA replication.
A population of sixteen emu grew to thirty-nine in one year. After two years, the population had grown to forty-eight. The maximum number of emu that the environment can support is approximately sixty due to limited resources such as food and water.
What is the carrying capacity of the emu population?
sixteen
thirty-nine
forty-eight
sixty
Answer: D. 60
Explanation: Answer is correct in Edge!!! TRUST ME!!! I'm Brainly!!! :)
The carrying capacity is the maximum number of individuals that an environment can support given its available resources and here that is approximately sixty that is the last option.
What is emu population carrying capacity?
in the case of the emu population, the environment may have limited resources such as food and water, which could limit the population size even if there are no other limiting factors. As the population grows, competition for resources could increase, making it harder for individuals to find enough food and water to survive and reproduce.
This could cause the growth rate to slow down or level off as the population approaches the carrying capacity. Other factors that could limit the emu population size include predation, disease, and habitat destruction. If there are predators that feed on emus, the population size could be limited by the availability of prey. Similarly, if there are diseases that affect emus, the population size could be limited by the spread of the disease.
Hence, approximately sixty is the carrying capacity in this case that is the last option.

What evidence supports a conservation law?
Carbon dioxide becomes glucose and oxygen during photosynthesis.
Hydrogen is made from the breakdown of carbon dioxide during photosynthesis.
Chlorophyll converts sunlight to chemical energy during photosynthesis.
Glucose and oxygen become carbon dioxide and water during photosynthesis.
Question 4(Multiple Choice Worth 4 points)
Answer:
it is c
Explanation:
C. Glucose and oxygen become carbon dioxide and water during photosynthesis.
Law of conservation:
A conservation law is a statement used in physics that says that the amount of something does not change in time.
In terms of Law of conservation of mass:
The "law of conservation of mass" is the conservation law that says that the amount of mass is always conserved, even if it is changed into another form.
During photosynthesis, plants take in carbon dioxide (CO₂) and water (H₂O) from the air and soil. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.Therefore, correct options that supports a conservation law is option C.

How did the invention of the microscope contribute to knowledge about 1p living things?
Answer:
It made it possible for people to discover and learn about cells.
Explanation:
The cell is the basic unit of structure and function of all living beings. A cell can also be defined as a morphological, functional, and reproductive unit of all living beings.
Every living organism is made up of one or more cells. All cells are created from an existing cell. A cell is the smallest unit that has all the characteristics of life. A set of cells of similar or the same appearance, embryonic origin, and function is called tissue.
The science that studies the cell is called cytology. There are organic and inorganic compounds in the cell. Of the inorganic compounds, water and salts are the most common. Organic compounds in the cell contain carbohydrates, fats, and proteins.

There are many different types of cells with many different types of cellular structures and functions. Which of these structures is found in all types of eukaryotic cells?
A. chloroplast
B. cell wall
C. nucleus
D. centrioles
Answer:
nucleus
Explanation:
chloroplasts and cell walls are only found in plant (and fungi) cells, while centrioles are only in animal cells.
The structure that is found in all types of eukaryotic cells is the nucleus. The correct option is C.
What are eukaryotic cells?Eukaryotic cells are those cells that contain true cell organelle. These cells are present in the higher organism, and they perform complex functions like replication, mitosis, etc.
There are two types of cells. They are prokaryotic and eukaryotic cells. Prokaryotic cells are those that do not contain an organelle and a nucleus. They are present in smaller organisms.
The nucleus is the brain of cells. It controls all functions of cells, and it contains the genetic material of the organisms. In prokaryotic cells, the nucleus is absent and in eukaryotic cells, the nucleus is present. That is the difference between them.
Thus, the correct option is C. nucleus.

7. B=brown eyes
b= blue eyes
What is true about these two brothers that have brown eyes:
One has genotype BB the other Bb.
a. they have same phenotype and genotype
b. they have different genotypes and phenotypes
c. they have same phenotype but different genotypes
d. they have same genotype but different phenotypes
The truth about these two brothers that have brown eyes is they have the same phenotype (Brown) but different genotypes (BB and Bb). So, the correct option is C.
What do you mean by Genotypes?Genotypes may be defined as a given set of alleles that an individual possesses. They are ultimate combinations of alleles.
In this situation, the allele B is dominant over the allele b, therefore, in both cases, phenotypes remain the same i.e. Brown eyes, but the genotypes differ. This defines how an allele interacts with another allele and changes the genotype.
Therefore, the truth about these two brothers that have brown eyes is they have the same phenotype (Brown) but different genotypes (BB and Bb).
