Part A: Design a food chain with four trophic levels, and identify the organism in each level. What happens to energy as it travels from the bottom up? (3 points)
Part B: Can humans ever occupy the lowest, or first, trophic level? Why or why not? (1 point)
Answer:
Part A: Primary producer - plants (ex: sunflowers), Primary consumers- herbivores(ex: rabbits), Secondary consumers - omnivores and carnivores (ex: snake), tertiary consumers - omnivores and carnivores (ex: foxes), A-p-e-x predators - can be omnivores or carnivores (ex: coyote)
Energy decreases as it travels from the bottom of an energy pyramid, every time energy passes from one tropic to another, the predator only gets 10% of the total energy, or the stored energy, the rest of the energy has already been used up.
Part B: Humans cannot ever occupy the lowest or first tropic level, because the first tropic level is for producers like plants, humans are not producers and therefore cannot be at the first tropic level.

Water reacts with minerals in some rocks and very slowly dissolves the rock. What type of weathering does this demonstrate?
Answer:
Salt wedging
Explanation:
Salt wedging is a natural phenomenon which occurs in rocks and stones. It is a physical weathering process. It is a process by which water enters into the small cracks on the rocks and form salt like NaCl and thereby enlarging the cracks.
Most water contains dissolved salts and when water enters into the small cracks of the rocks, the salt begins to grow and it exerts pressures on the walls of the crack thereby enlarging the cracks.
This type of phenomenon is mostly seen near the seacoast and in the arid regions.
Thus water reacts with the minerals in the rock and slowly dissolves the rock in salt wedging weathering process.

O2. 3-phosphoglycerate. glucose. glyceraldehyde 3-phosphate (G3P).
Answer:
Option B, O2
Explanation:
It is because the oxygen released during the process of photosynthesis comes from the water absorbed by the roots and not by the CO2containing heavy oxygen (18O). In fact oxygen from CO2 containing heavy oxygen (18O) is used in making sugar which is then stored for energy.
Hence, option B is correct

The different forms of the beef cattle color gene are called_
The different forms of the beef cattle color gene are called "alleles"
What are alleles?Alleles are alternative versions of a gene that arise from mutations and are located at the same position on a chromosome.
In the case of beef cattle, the color of the animal is determined by the interaction of multiple genes, including the color gene. The color gene can have different alleles that influence the color of the animal's coat. For example, one allele may result in a black coat color, while another allele may result in a red coat color.
The combination of alleles that an animal inherits from its parents determines its genotype, which in turn determines its phenotype or observed traits. Therefore, the different alleles of the beef cattle color gene can result in different coat colors, patterns, and markings in the cattle population.

6. Catalase is an enzyme that speeds up the breakdown of hydrogen peroxide. The enzyme increases the rate of reaction, so it is 700 times faster. If the enzyme reaction took 1.9s how long would the reaction take if there was no enzyme? Convert the answer to minutes. Give your answer to 4sf.
Answer:
0.00004524 minute
Explanation:
The enzyme is Catalase, and it speeds up the rate of reaction by 700 times than what it was supposed to be.
If the already sped up rate of reaction is 1.9 seconds, then the initial reaction ought to have taken
1.9/700 seconds and that is 0.0027143 second.
We're asked to convert to minute, we then have
0.0027143/60 which is equal to 0.0000452381 minute.
Since we're asked to round off to 4 significant figure, we have 0.00004524 minute.

Pollen and Ovules are gametes. How many chromosomes would they have compared to the rest of the plant's body cells? What process made them that way?
Answer:
a. They would have half chromosomes as much as the plants body cells.
b. Meiosis
Explanation:
Gametes are sex cells produced only in sexually reproducing organisms. In plants as stated in this question, male gametes are contained in pollens while female gametes are contained in ovules. The process by which these gametes are made is called MEIOSIS.
Meiosis is a cell division that reduces the chromosomal number of the parent cell by half. This means that each GAMETE will contain half the number of chromosomes as the parent cell. Fir example, if the body cell of a plant contains 30 chromosomes, each gamete formed via Meiosis in that plant will have 15 chromosomes.
In a nutshell, pollen and ovules, which are gametes of plants formed by MEIOSIS would have half chromosomes as much as the plants body cells.

2]gland
3]pancreas
4]thyroid
Answer: 2]gland brainliest?
Explanation:
Plants need three things for photosynthesis to occur: water, carbon dioxide and sunlight. How do those things enter a plant? Water, along with important minerals, enters a plant from the soil where the plant's roots act like straws "drinking" it up. Carbon dioxide enters a plant from the atmosphere, and it comes in through the leaves. More specifically, carbon dioxide enters a plant through tiny pores or openings on leaves called stomata. Sunlight, obviously, comes from the sun. But how does it enter the plant to be converted into chemical energy that the plant can use? Well, green plants are green because of a pigment called chlorophyll. That pigment inside of plant cells absorbs the sun's energy, making it possible for photosynthesis to occur.
Based on the passage, if human cells had a lot of chlorophyll, they would most likely
A
not need to drink water.
B
be green.
C
breathe carbon dioxide.
D

Why do we use specific terminology when referring to the gender and species of common domestic animals?
Answer:
To know which exact organism you are referring to, and there is no confusion about it.
Explanation:
To identify organisms, we usually use two names. The common name and the scientific one.
Scientific name: binomial nomenclature.
The scientific name designates a species through binomial nomenclature. The binomial nomenclature is a standard agreement used to identify different organisms. It has international validity, and it does not change among regions or languages. One binomial name is used only on one organism and can not repeat. It is composed of two Latin words: gender and the specific name. Many species might share the same gender for being very similar, so the specific name is used to identify each species.
Common names:
These are informal names, determined by the people of a region or area, that speak the same language. They are regional names, so they change from region to region, even when referring to the same organism. Usually, these names designate only organisms that have importance for the people. The same name might refer to different organisms, and in many cases, the same organism might receive many names. For this reason, there might be confusion when using only common names to talk about a species.
If we need to refer to a particular organism, we should always use the scientific name to avoid confusion. As it is internationally recognized and accepted, anybody can know which species you are talking about, independently of the region or the language. In most cases, people mention a species using the scientific name together with many of its common names.
Describe the functions and organization of tissue systems in a seed plant.
Answer:
tissues is the protect outer covering of plants
Explanation:
Plants consist of many different types of cells that are organized into aggregates called tissues. Tissues are derived from specialized groups of dividing cells called meristems. Meristems are the source of cells and tissues and therefore they are not strictly speaking tissues themselves
Plants are multicellular eukaryotes with organized tissue and specialized organs with specific tasks.
What are the functions and organization of the tissue system in a seed plant?Plants are multicellular eukaryotes, and their tissue systems are made up of many cell types that serve distinct purposes. Meristematic tissue and permanent (or non-meristematic) tissue are the two main forms of plant tissue systems. Meristems, which are areas of plants that experience continuous cell division and expansion, are where the meristematic tissue's cells may be located. Meristematic tissue cells continue to divide and support plant growth despite being either undifferentiated or incompletely differentiated. Permanent tissue is made up of dormant plant cells, which are no longer actively dividing.Secondary tissues can be simple (made up of similar cell types) or complex (composed of different cell types). Dermal tissue is a simple tissue that covers the plant's exterior and regulates gas exchange. One example of a complex tissue is vascular tissue, which is composed of the specialized conducting tissues xylem and phloem.To learn more about the functions and organization of the tissue system in a seed plant, refer to https://brainly.com/question/17774097

Which of the following best predicts and justifies how the proportion of the Tibetan population with big blood vessels living in the mountains will change over the next 1,000 years (assuming conditions remain stable)?
Question 2 options:
I predict that the proportion of individuals with big blood vessels living in the mountains will decrease because there is a variation in blood vessel size and those with the smaller blood vessels can store more red blood cells than larger vessels, so more oxygen can be moved to the body cells. Therefore, they have a better chance of surviving and passing this trait on to their offspring.
I predict that the proportion of individuals with big blood vessels living in the mountains will stay the same because there is a variation in blood vessel size and that variation will remain in a population. The is what is so cool about humans, we are all so unique.
I predict that the proportion of individuals with big blood vessels living in the mountains will increase because there is a variation in blood vessel size and those with the bigger blood vessels can deliver more oxygen to the body cells and therefore have a better chance of surviving and passing this trait on to their offspring.
I predict that over 1,000 years, the proportion of individuals with big blood vessels living in the mountains will not change because a change can’t happen to an individual, an individual can only increase the amount of red blood cells it makes, not its blood vessels.
