Energy cannot be produced by fungi and heterotrophic organisms
Answer:
No they cannot
Explanation:
Fungi, which are also heterotrophs as well as other heterotrophic organisms cannot produce their own energy for their own function because they do no make their own food. That is they do not have chloroplasts and therefore obtain energy from autotrophs ( organisms that make their own food for energy)
Due to a genetic modification, a mouse has no horizontal cells in its retinas. What impact will this have on the mouse’s vision?
Answer:
Below
Explanation:
Horizontal cells are the laterally interconnecting neurons having cell bodies in the inner nuclear layer of the retina of vertebrate eyes. They help integrate and regulate the input from multiple photoreceptor cells. Without them you wouldn't be able to see color, which means the mouse won't process color.
Due to a genetic modification, a mouse has no horizontal cells in its retinas and it does not expresses the connexin26.

How did gravity affect the growth of the germinating corn seeds?
Answer:
see below
Explanation:
their roots respond positively, growing down, into the soil, and their stems respond negatively, growing upward, to reach the sunlight.
Gravity influenced the growth of germinating corn seeds by providing the directional cue for root growth and promoting proper orientation of the plant.
Gravity plays a crucial role in plant growth and development, particularly during the germination of seeds. When a germinating corn seed is placed in a gravitational field, gravity acts as a guidance mechanism for the growing seedling.
In response to gravity, the root of the germinating seed grows in a downward direction, a process known as gravitropism or geotropism. This downward growth of the root is called positive gravitropism. The root responds to the gravity stimulus by redistributing auxin, a plant hormone, towards the lower side of the root. This causes cells on the lower side of the root to elongate more than cells on the upper side, leading to downward growth. The downward growth of the root helps anchor the plant in the soil and facilitates water and nutrient absorption from the ground.
Simultaneously, gravity also influences the shoot of the germinating corn seed. The shoot exhibits negative gravitropism, where it grows upward against the force of gravity. This upward growth is counterbalanced by the downward growth of the root, allowing the plant to establish proper orientation.
Without the presence of gravity, the germinating corn seeds would not be able to establish the proper orientation and direction of growth. The root may not grow downward, leading to irregular and inefficient water and nutrient absorption. The shoot may not grow upward, resulting in an abnormal and compromised overall plant structure.
Therefore, gravity serves as a crucial external factor that guides the growth of germinating corn seeds, ensuring proper root development, anchorage, and shoot orientation for successful plant growth.

If a srna is bound to the ribosome binding sequence of a mrna coding for an enzyme in a bacteria, what effect will this have on the amount of enzyme in this cell?.
If an sRNA is bound to the ribosome binding sequence of an mRNA coding for an enzyme in a bacteria, it will reduce the amount of enzyme.
What is an sRNA?A small RNA (sRNA) is a short sequence that binds to target mRNAs by base complementarity and thus reduces gene expression.
These sequences (sRNAs) can efficiently block prokaryotic translation in order to reduce the amount of protein.
The sRNAs have fundamental regulatory roles both in bacterial translation and protein production.

Taxa in the Linnaean system include the kingdom, phylum, class, order, family, genus, and species. Linnaeus also developed binomial nomenclature for naming species.
Plants manufacture their own supplies of carbohydrate. What are the raw materials and the waste product of this process? raw materials waste product A. Carbon dioxide and chlorophyll oxygen. B. carbon dioxide and water oxygen. C. oxygen and chlorophyll carbon dioxide. D. oxygen and water carbon dioxide.
Answer:
Carbon dioxide, water, and sunlight are the raw materials for photosynthesis. Photosynthesis is the process by which green plants make their own food from carbon dioxide and water in the presence of sunlight. The prepared food is glucose. To prepare one molecule of glucose, by the process of photosynthesis six molecules of carbon dioxide and six molecules of water is required. Six oxygen molecule is released as a byproduct.
Thus, the correct product are 'Carbon dioxide, water, and sunlight'.

A 30.0 x 10^8 L sample of nitrogen inside a rigid, metal container at 19.50 °C is placed inside an oven whose temperature is 78.50 °C. The pressure inside the container at 19.50 °C was at 864.5 psi. What is the pressure of the nitrogen after its temperature is increased?
Answer:
Answer:
3.31 atm.
Explanation:
Gay-Lussac's law states that for a given mass and constant volume of an ideal gas, the pressure exerted on the sides of its container is directly proportional to its absolute temperature.
∵ P α T.
∴ P₁T₂ = P₂T₁.
P₁ = 3.00 atm, T₁ = 20.0 °C + 273.15 = 293.15 K.
P₂ = ??? atm, T₂ = 50.0 °C + 273.15 = 323.15 K.
∴ P₂ = (P₁T₂)/T₁ = (3.00 atm)( 323.15 K)/(293.15 K) = 3.307 atm ≅ 3.31 atm.
