HELPPPPPPPPPPPP!!!!!!!!!!!!!!!!!!!!!!!! All of the following cause mechanical weathering EXCEPT ____. a. ice c. burrowing animals b. tree roots d. carbonic acid
Explanation:
c. burrowing animals is the answer
1）Fishing boats have decreased the number of herring in the sea. Explain why that could affect the number of offspring puffins can raise.
2） Which animals have a bigger food supply now there are fewer herrings?
3） Global warming is expected to reduce the biomass of phytoplankton in the oceans. What effect will that have on the rest of the food web?
Explanation:
1) When the number of herrings decrease, the food available for the puffins decrease and therefore they will not be able to feed their offspring. This will cause the number of offspring to decrease.
2) Any other animal(s) which hunts and eats the same prey as a herring will now have a bigger food supply.
3) When the biomass of phytoplankton decrease, the next animal in the food web will not have any food and their numbers will decrease, decreasing the number of the animals next in the web, as they too lose their food. This will continue for the rest of the food web and the number of animals will decrease.
What is conservation genetics?Question 82 options: conserving a species genome so that it is best adapted to the current environment harvesting and saving samples of species genomes from distinct time periods a way to inform conservation efforts based on genetic information from species techniques that preserve a low genetic diversity of an ecosystem the use of genetically modified organisms (GMOs) to strength a particular ecosystem
Answer:
a way to inform conservation efforts based on genetic information from species
Explanation:
Genetic studies in wildlife and captivity species provide significant information to understand aspects regarding the biology and ecology of species, especially endangered species. Many discoveries have been useful to solve several taxonomic issues, determine the risk of diseases, and explain reproductive problems, among other problems. What is even more important is that genetic knowledge helps to plan management programs and conservation. Together with other areas related to behavior and conservation, genetic knowledge provides the basis to carry out successful conservation strategies.

In a separate maddyase experiment using (Et)-10nM, the reaction velocity is measured as 3uMS. What is the substrate concentration used in the experiment
Answer: hello your question has some missing data attached below is the missing data
Applying the Michaelis-Menten Equation
An enzyme is found that catalyzes the reaction X ⇋ Y Researchers find that kcat for this enzyme is 600s^-1 and carry out several additional experiments.
answer :
substrate concentration [ x ] = 10⁻⁵ M
Explanation:
Given data:
[Et ] = 10 * 10⁻⁹ M ,
Reaction velocity ( V₀ ) = 3* 10⁻⁶ Ms⁻¹
applying Michaelis-Menten Equation
= 3* 10⁻⁶ = [tex]\frac{600 *10*10^{-9} * (X) }{10^{-5} + (X) }[/tex] ,
= ( 3 * 10⁻⁶ )( x ) + ( 3 * 10⁻¹¹ ) = ( 6 * 10⁻⁶ ) ( x )
hence the substrate concentration [ x ] = 10⁻⁵ M

oil-rich countries in the middle east cover about 4% of earth's total land area but posses about 48% of the world's known oil reserves. what is the main reason for high concentration of reserves in this part of the world?
The correct answer is A. Geological processes.
Explanation
Oil is a hydrocarbon of fossil origin by geological processes that transforms large amounts of organic matter deposited on anoxic bottoms of seas or lake areas of the geological past, which were later covered by heavy layers of sediment. This causes organic materials to be transformed into oil by the heat and pressure of the upper layers. However, this phenomenon does not occur in all parts of the earth because in some, as in the case of the Middle East, there were large amounts of organic matter that became an oil reserve. So the correct answer is A.

D. “chloroplasts” should be “mitochondria”
Photosynthesis is a chemical reaction that takes place in the chloroplasts of green plant cells, where light energy is used to convert carbon dioxide and water into glucose and oxygen. Option A is the right answer.
What is photosynthesis?Photosynthesis is the process by which green plants prepare their own nutrients with the help of sunlight, water, and carbon dioxide.
Photosynthesis helps plants to prepare their own food, these plans are called autographs.Photosynthesis takes place inside the protoplast.This process takes place in some other organisms other than green plants.Chlorophyll is the green pigment that is required for this process to take place.The end products that are formed in the process of photosynthesis are glucose and water.Hence Option A is the right answer.

For some parents, their offspring have larger beak depths; for others it's smaller. How does the concept of variation of traits help to explain this?
Answer:
beak depth is a complex (quantitative) trait
Explanation:
Additive effects refer to the resulting effects of two or more genes acting together. Beak depth is a quantitative trait whose variation is determined by the additive effects of many genes acting together and the environment. In quantitative traits, variation is continuous and produces a range of phenotypes. In consequence, in this case, some offspring will have a larger average beak depth compared to their parents, whereas others will have a smaller average beak depth compared to their parents. It is due to the combination of alleles or 'additive effects' inherited from different parents, and the interaction between these genes and the environment. Heritability refers to the proportion of quantitative trait variation due to additive genetic factors: a higher heritability is due to the predominance of additive genetic effects and less influenced by environmental effects.
Mateo and Tomás are identical twins. Mateo was raised by his father and mother, and Tomás was
accidentally placed with another family after a mix-up at the hospital. At the age of 15, the boys ran into
each other at a football game and noticed that they appeared to be mirror images of each other. After
genetic testing proved that they are twins, the families discussed some of the differences between the boys.
Mateo is very athletic and intelligent and excels in basketball, but he does not take school seriously and has
F's in all subjects. Tomás is also athletic and intelligent and excels in baseball, and he makes straight A's as
a result of his strict home life and study routine. Although they are identical twins, what do you think
accounts for the differences in the two boys' academic performance based on the research?

describe how the structure of the cuticle, palisade mesophyll, spongy mesophyll and guard cells are adapted for their functions
Answer:
cuticle
In some higher plants, the cuticle is a water-impervious protective layer covering the epidermal cells of leaves and other parts and limiting water loss. It consists of cutin, a waxy, water-repellent substance allied to suberin, which is found in the cell walls of corky tissue.
adapted( function)
The cuticle reduces the rate of water loss from the leaf surface. Other leaves may have small hairs (trichomes) on the leaf surface. ... They can also reduce the rate of transpiration by blocking air flow across the leaf surface.
palisade mesophyll
Light absorption happens in the palisade mesophyll tissue of the leaf. Palisade cells are column shaped and packed with many chloroplasts . They are arranged closely together so that a lot of light energy can be absorbed.
adapted ( function)
The palisade mesophyll layer of the leaf is adapted to absorb light efficiently. The cells: are packed with many chloroplasts. are column-shaped and arranged closely together
spongy mesophyll
Spongy mesophyll tissue is packed loosely for efficient gas exchange. The spongy mesophyll cells are covered by a thin layer of water. Gases dissolve in this water as they move into and out of the cells. ... To enter the leaf, gases diffuse through small pores called stomata.
adapted (function)
Spongy mesophyll tissue is packed loosely for efficient gas exchange. The spongy mesophyll cells are covered by a thin layer of water.When the plant is photosynthesising during the day, these features allow carbon dioxide to diffuse into the spongy mesophyll cells, and oxygen to diffuse out of them
Guard cell
Guard cells are cells surrounding each stoma. They help to regulate the rate of transpiration by opening and closing the stomata. Light is the main trigger for the opening or closing. Each guard cell has a relatively thick cuticle on the pore-side and a thin one opposite it.
Adapted (function)
Guard cells are adapted to their function by allowing gas exchange and controlling water loss within the leaf. The size of the stomatal opening is used by the plant to control the rate of transpiration and therefore limit the levels of water loss from the leaf. This helps to stop the plant from wilting

After photosynthesis, how will producers get their energy? Producers receive glucose from the intake of oxygen. Producers will release glucose into the atmosphere, feeding the ecosystem. Producers will create glucose, which is the primary source of food. Producers will receive glucose directly from any rainfall that occurs.
Answer:
After photosynthesis (Producers will create glucose, which is the primary source of food)
Explanation:
The biotic component of an ecosystem is made up of all living organisms in it. These organisms are divided into two main groups according to the way they feed:
--> Producers (autotrophs) and
--> Heterotrophs.
Producers are organisms that are able to use sunlight or chemical energy to manufacture their own food (glucose) from simple inorganic substances. This process is known as photosynthesis. Producers include all green plants, photosynthetic protists and some bacteria
Producers extract inorganic nutrients and chemical energy from their non-living environment, that is, from the abiotic component of the ecosystem. Since autotrophs are the only organisms that can produce food in an ecosystem, they are also known as PRIMARY FOOD PRODUCERS.
PRODUCERS use some of the food they produce for their activities and building their body tissues (growth). The rest is stored in various parts of the body.
Answer: Its C, Producers will create glucose, which is the primary source of food.

Though plants, fungi, and prokaryotes all have cell walls, we place them in different taxa. Which of these observations comes closest to explaining the basis for placing these organisms in different taxa, well before relevant data from molecular systematics became available?
Answer:
Due to other differences.
Explanation:
The plants, fungi, and prokaryotes all have cell walls, we place them in different taxa because of the other differences such as mobility, mode of nutrition etc. Plants and fungi are not mobile means can not move from one place to another whereas prokaryotes are mobile. Fungi and prokaryotes are heterotrophs means that feed on other organism whereas plants are autotrophs means make their own food. There is also difference in their cell wall i.e. the cell of plants is composed of cellulose, the cell wall of prokaryotes especially bacteria is composed of peptidoglycans and the cell wall of fungi is composed of chitin.
