why are saprophytes and parasites considered heterotrophs?
Answer:
While a good number of saprophytes (e.g. many fungi) may possess plant-like traits, they are unable to produce their own food and therefore have to ingest organic compounds as their source of energy. It is for this reason that they are classified as heterotrophs

This model shows a human embryo. What can you determine about its development from the model?
It has a postanal tail.
It’s a vertebrate
It has pharyngeal arches.
It has fully developed organ systems.
In humans, tails are vestigial structures, meaning the embryo can express it in early stages of development, but then, they loose it. Option A) It has a postanal tail.
What is a vestigial structure?Vestigial structures are those body parts that have lost or reduced their original function during the evolution of a species.
These vestigial structures might be found in many animals, including human beings. They were plenty functional in the ancestors of new species, but now are typically degenerate, stunted, or rudimentary, and tend to be much more variable than homologous non-vestigial parts.
An example of these structures is the coccyx. This tailbone is the remnant of a missing tail. Actually, all mammals have a tail at some point in their development, even in humans, it is present for a period of 4 weeks during embryogenesis, but after a period of time this tail disappears and its forming vertebras get fussed with each other composing the coccyx.
In many animals, the function of the tail is to stabilize, equilibrate and mobilize. But in humans, the coccyx, located at the end of the vertebral column, has lost this original function. Although it is still an area of muscle insertion.
The correct option is A) It has a postanal tail.

What factor affects the temperature of ocean water?
Answer:
The following factors affect the distribution of temperature of ocean water: (1) Latitudes: The temperature of surface water decreases from equator towards the poles because the sun’s rays become more and more slanting and thus the amount of insolation decreases poleward accordingly.
Explanation:
Answer:
Depth
Explanation:
The ocean has three layers from the top to bottom containing different temperatures. The first layer is of warm oceanic water approximately 500 m think containing temperatures of about 20 degrees Celsius to 25 degrees Celsius. The second layer is the thermocline layer characterized by a decreasing temperature with increased depth. The last layer is that of very cold temperature that extends to the deep ocean floor. There are other factors which affect the distribution of temperature of ocean water which include: latitudes, unequal distribution of land and water, prevailing wind and ocean currents.
______ and _____ factors cam effect an organisms trait
Explanation: Genes are encoded with different traits. Each of these traits carries different functions to the new offspring that is developing. ... The genes that an organism inherits can affect gene function. For example, they can have a recessive gene for something that might affect them. I hope that this helps you out, have a fantastic day!!
The factors that influence the organism trait are the gene and environmental factors, as a result of that, organisms are controlled and regulated in a certain way, and the animals in the rainforest are different from those in the savanna due to this.
What is the significance of the traits and their regulators?Traits are determined by the combination of genetic and environmental factors, such as temperature, light, and nutrition, which affect the expression of genes and the development of an organism's traits, as exposure to certain pollutants leads to mutations in an organism's genetic material.
Hence, the factors that influence the organism trait are the gene and environmental factors, as a result of that, organisms are controlled and regulated in a certain way, and the animals in the rainforest are different from those in the savanna due to this.

How much energy is passed from plants to primary consumers?
Answer:
Explanation: Primary consumers only obtain a fraction of the total solar energy about 10% captured by the producers they eat. The other 90% is used by the producer for growth, reproduction, and survival, or it is lost as heat. You can probably see where this is going. Primary consumers are eaten by secondary consumers.

Answer:
c. move by diffusion from outside to inside the cell.
Explanation:
Hi, I'm Isabell G, I'm in actually in your same period lol. I'm not sure if you already did it but yeah here's the answer. I checked it after I submitted it, it's correct.
If a substance is more highly concentrated outside the cell than inside the cell and the substance can move through the cell membrane, the substance will move by diffusion
What are diffusion and its importance?
Diffusion is the transfer of individual molecules of material from a region of higher concentration to a region of lower concentration over a semipermeable barrier
Cells depend on diffusion to get the nutrients they need to develop and obtain energy as well as to rid themselves of waste materials. It helps in gaseous exchange during respiration in organisms.
Thus, when a substance is more highly concentrated outside the cell than inside the cell and the substance can move through the cell membrane, then the substance will move by diffusion

Genes, the environment, and the organism
The net outcome of the reading of a gene is that a protein is made that generally has one of two basic functions, depending on the gene. First, the protein may be a structural protein, contributing to the physical properties of cells or organisms. Examples are microtubule, muscle, and hair proteins. Second, the protein may be an enzyme that catalyzes one of the chemical reactions of the cell. Therefore, by coding for proteins, genes determine two important facets of biological structure and function. However, genes cannot dictate the structure of an organism by themselves. The other crucial component in the formula is the environment. The environment influences gene action in many ways, about which we shall learn in subsequent chapters. In the present context, however, it is relevant to note that the environment provides the raw materials for the synthetic processes controlled by genes. For example, animals obtain several of the amino acids for their proteins as part of their diet. Most of the chemical syntheses in plant cells use carbon atoms taken from the air as carbon dioxide. Bacteria and fungi absorb from their surroundings many substances that are simply treated as carbon and nitrogen skeletons, and their enzymes convert these components into the compounds that constitute the living cell. Thus, through genes, an organism builds the orderly process that we call life out of disorderly environmental materials

B. net 2 NAD+, 2 ATP, 4 CO2, 2 FADH
C. net 4 NADH, 4 ATP, 8 CO2, 4 FADH2
D. net 1 NADH, 1 ATP, 2 CO2, 1 FADH2
Answer:
Its A
Net 2 NADH, 2 ATP, 4 CO2, 2 FADH2
The Krebs cycle forms 2 NADH, 2 ATP, 4 CO2 and 2 FADH2 after one molecule of glucose goes through it. So the correct option is A.
What is the Krebs cycle?The Krebs cycle is also known as the TCA cycle (tricarboxylic acid) or the citric acid cycle. It is the main source of cellular energy and an important part of the entire process of aerobic respiration.
In this cycle, the available energy of Acetyl coenzyme A is utilized and converted to Nicotinamide Adenine Dinucleotide (NADH). In glycolysis, glucose is utilized to form pyruvate. The pyruvate is oxidized to Acetyl coenzyme A and then it enters the TCA cycle.
The intermediates involved in the pathway also form intermediates for many other pathways to form porphyrins, amino acids, fatty acids etc. Thus, any disturbance in this cycle will not only disturb itself but many other pathways.
Therefore, the end products of the Krebs cycle are 2 NADH, 2 ATP, 4 CO2 and 2 FADH2. Hence the correct option is A.

Hemophilia is a recessive sex-linked disorder (Xh). A man with hemophilia and a female carrier are concerned about their daughter inheriting the disorder. Use a punnett square explain to these parents the probability (percent chance) that their daughter could have the disorder.
Answer:
The chances of a hemophilic man and a female carrier having a that one of their daughters inherits the disease are 25%.
Explanation:
Since hemophilia is a disease with a sex-linked recessive inheritance pattern —X chromosome— all males who acquire the altered gene will have hemophilia ([tex]X^{h}[/tex]Y), while a female should have both altered chromosomes ([tex]X^{h}[/tex]X) to manifest the disease.
If a hemophilic male and a female carrier of the hemophilia gene have children, the possibility of having a daughter with hemophilia can be seen by crossing.
♂ [tex]X^{h}[/tex]Y♀ [tex]X^{h}[/tex]XAlleles [tex]X^{h}[/tex] Y
[tex]X^{h}[/tex] [tex]X^{h}[/tex][tex]X^{h}[/tex] [tex]X^{h}[/tex]Y
X [tex]X^{h}[/tex]X XY
In the offspring, there are:
Healthy sons 25%.Hemophilic sons 25%.Carrier daughters 25%.Hemophilic daughters 25%.The hemophilic man and the carrier woman should know that they have a 25% chance of having a hemophilic daughter, or that 50% of their daughters may have the disease.
