Auxins cause cells to grow ___. A. Longer on the sunny side of the stem. B. Shorter on the sunny side of the stem . C.shorter on the shaded side of the stem .d. Longer on the shades side of the stem
Answer:
D. Longer on the shaded side of the stem
Explanation:
Auxin is a plant hormone that promotes cell growth and elongation in plant stems.
It causes the cells to grow longer on the shaded side of the stem.
This growth allows for the plant to grow in the direction of the light source it has.
So, the correct answer is D. Longer on the shaded side of the stem

The fossil presence of anatomically modern humans in ________ demonstrates that our ancestors were capable of substantial water crossings by 40,000 years ago.
Answer:
The correct answer is - Africa.
Explanation:
Scientists found the fossils of modern humans called Mota an ancient man who lived around 40000 to 45000 years ago in Ethiopia. It was the first DNA isolated from Africa.
This DNA sample says that the Europeans have 6% of the DNA of this modern human, which suggests that there was substantial migration of people into Africa from Europe and the middle east by water crossings.
Drag a number and symbol to represent the amount of time Carl worked on problems.
___ ___ ____
Answer:
25 - m
Explanation:
If Carl worked m less than 25, 25 - m would represent the amount of time Davis worked minus the difference in the amount of time that he and Carl worked, which would equal the amount of time Carl worked.
Explain the advantages to a plant of having its cell membranes surrounded by cell walls
Answer:
Advantage of cell walls
It protect and support the cell .
To give difinite shape for the cell.
Having cell walls surrounding cell membranes provides several advantages to plants, including structural support, protection against pathogens, regulation of water balance, and prevention of cell rupture.
The cell wall is a rigid structure located outside the cell membrane in plant cells. It is composed primarily of cellulose, a complex carbohydrate. Here are the advantages of having cell walls:
Structural Support: Cell walls provide mechanical support to plant cells and help maintain the overall shape and structure of the plant. They allow plants to stand upright and withstand environmental forces such as wind or gravity. The cell walls of adjacent plant cells are interconnected, forming a strong network that provides stability to the plant as a whole.
Pathogen Protection: The cell wall acts as a physical barrier against pathogens such as bacteria and fungi. It prevents the entry of pathogens into the plant cells, reducing the risk of infection. Additionally, the cell wall can contain antimicrobial compounds and other defense molecules that provide further protection against pathogens.
Water Regulation: The cell wall plays a crucial role in regulating water balance within plant cells. It helps maintain turgor pressure, which is essential for cell expansion and overall plant growth. The cell wall allows water to enter and exit the cell in a controlled manner, preventing excessive water uptake or loss.
Cell Rupture Prevention: The rigid cell wall helps prevent cell rupture or bursting when the internal pressure within the cell increases. It provides strength and stability to the cell, allowing it to withstand internal pressure changes without bursting.
Overall, the presence of cell walls in plant cells offers significant advantages in terms of structural support, protection against pathogens, regulation of water balance, and prevention of cell rupture. These advantages contribute to the overall health, growth, and survival of plants in diverse environmental conditions.

In meteorology, ____ is a volume of air defined by its temperature and water vapor content.
Answer:
mass
Explanation:
An Air mass is a volume of air defined by its temperature and water vapor content. A front is the border between two air masses.
In meteorology, mass is a volume of air defined by its temperature and water vapor content.
What is meteorology?In the academic, public, and private sectors (government and business), meteorologists work in these fields. Some of the businesses and organizations who employ meteorologists or make use of various meteorological services.
Although we will touch on a few other topics as well, the main focus of this course will be on weather analysis and forecasting. After all, everyone is affected by the weather every single day in some way.
Meteorology is defined as "the science of the atmosphere covering both weather and climate" in the Met Office's Meteorological Glossary.
Therefore, In meteorology, mass is a volume of air defined by its temperature and water vapor content.

Why is it more difficult for top carnivores to obtain sufficient energy resources than it is for animals lower on the food chain?
the trophic pyramid is the reason
what the trophic pyramid is: Trophic pyramid, also called an energy pyramid, showing the progression of food energy. The pyramid base contains producers, organisms that make their own food from inorganic substances. All other organisms in the pyramid are consumers
- predators get little energy from the prey they eat so they must consume multiple prey
It is more difficult for top carnivores to obtain sufficient energy resources than it is for animals lower on the food chain because the higher trophic levels have less energy than the lower ones.
The trophic levels of food chainThe food chain is defined as a feeding pathway that consists of similar organisms that are placed in the same trophic levels.
Trophic levels in a food chain are those levels that is occupied by a group of organisms that have a similar feeding mode.
The plants which are the producers are at the lower trophic level while the carnivores are at the higher trophic levels.
The carnivores eats meat from other animals but not plant or plant products which obtain direct energy from sunlight.
Therefore, It is more difficult for top carnivores to obtain sufficient energy resources than it is for animals lower on the food chain because the higher trophic levels have less energy than the lower ones.

A pair of identical twins develop leukemias, where immature white blood cells proliferate uncontrollably. In each case, the cancer cells analyzed from identical twins displayed an identical chromosomal mutation and this critical mutation was not found in the twins normal cells. The twins developed leukemia at different times in their lives. What is the best explanation for the origin of this chromosomal mutation
Answer:
The chromosomal rearrangement resulted from a rare somatic mutational event that occurred in utero
Explanation:
Leukemia is a progressive type of cancer where immature white blood cells (leukocytes) proliferate uncontrollably. Next-generation sequencing (NGS) technologies have shown that somatic mutations are relatively common in different types of leukemia such as, for example, acute myeloid leukemia (AML). Moreover, identical twins are developed from one fertilized egg (ovum) that splits and develops into two identical individuals that share all of their genes (i.e., they have exactly the same genetic information). In this case, it is expected that leukemogenesis was initiated in the utero by the occurrence of a chromosomal rearrangement and proceeded early during development as distinct clonalities. In addition, the fact that identical twins developed leukemia at different times in their lives also indicates that this malignancy wasn't caused by only one mutation, but instead it was triggered by multiple mutational events (i.e., leukemia is a multistep cancer caused by secondary genetic changes).
