One trait a plant can have is either red leaves (R) or brown leaves (r). Another trait is tall stems (T) or short stems (t). A plant used in a dihybrid cross has the genotype RrTt. What is the phenotype of this plant?

Answers

Answer 1

Answer: The upper-case letters generally refer to a dominant allele, meaning that if it is present in the genotype, it will be present in the phenotype. Therefore, a plant with genotype RrTt has the dominant alleles for both traits, and thus expresses these genes, giving a phenotype of a (R)ed leafed plant with (T)all stems.

Answer 2

Answer:

Answer:

Red leaves, tall stem

The food web above represents feeding relationships in a biological community near a deep-sea hydrothermal vent. Hydrothermal vents are geysers on the seafloor that gush super-heated, mineral-rich water. The seawater surrounding hydrothermal vents typically contains carbon dioxide (CO2), molecular hydrogen (H2), hydrogen sulfide (H2S), and methane (CH4). Sunlight, however, fails to reach the seafloor where deep-sea hydrothermal vents are located.As part of an investigation, researchers collected living specimens from an area near a deep-sea hydrothermal vent. Mussels in the collection were found to be dependent on molecular hydrogen in seawater. Also, the researchers discovered multiple species of bacteria living in the gills of the mussels. Mussels use gills for filter-feeding and gas exchange with the surrounding seawater. On the basis of their experimental results, the researchers hypothesized that some bacteria living in the gills of the mussels are capable of chemosynthesis. Based on an analysis of the food web, an observation that deep-sea bacteria consume molecular hydrogen (H2) is most relevant to resolving which of the following apparent contradictions?Some organisms rely on energy captured from inorganic compounds to drive basic biological processes.Some deep-sea organisms appear to be primary consumers, but no plants live near the hydrothermal vents.

Please can you help me explain three ways how cities can reduce the effects of an earthquake? Thank you! :3

Answers

1. You can build Earthquake resistant buildings- These are built with deep foundations. From rubber absorbers to concrete reinforced with steel.

2.Earthquake drill- They do this in Japan. and they basically practise what to do in the event of an actual earthquake happening

3. you can also be prepared. Have extra food and water.

Unnatural occurrences can have the most significant impact on an ecosystem. True

Answers

Answer: True

Explanation:

Unnatural occurences are those catastrophic events induced by humans which can exert drastic impact over the ecosystem. These may include deforestation, forest fire, intentional explosion, and others. This will result in loss of many species due to damage caused to the non-living physical environment.

If your question is true or false, my answer is True.
Because any unnatural occurrences like building houses can change the ecosystem a lot.
When we build a house we are destroying some animals house.

All parts of fungi are composed of ____________ , or thin filaments of cells, packed closely together to form the main body of a fungus called the ____________ .

Answers

The right answer is hyphae for the first gap, mycelium for the second gap.

The hyphae constitute the vegetative apparatus of the mushrooms, while the visible part, that which is improperly called mushroom, is in fact its reproductive apparatus.

Hyphae are less branched filaments consisting of a single cell that can be several centimeters long. They contain several nuclei and can sometimes be partitioned.

The mycelium is a part of the mushroom (composed by many hyphae), which is in the form of white filaments and grows about fifteen centimeters under the ground. It is this part of the mushroom that has therapeutic properties because the filaments of the mycelium are going to draw the minerals in the soil.

Protists from which of the following taxonomic groups are most likely to lead to paralytic shellfish poisoning? Protists from which of the following taxonomic groups are most likely to lead to paralytic shellfish poisoning? A. Toxoplasma
B. Plasmodium
C. Euglena
D. Giardia
E. Dinoflagellata

Answers

Paralytic shellfish poisoning.

Explanation:

The taxonomic group which is more likely to cause shellfish poisoning is :

E. Dinoflagellata.

Paralytic shell fish poisoning is a serious food poisoning caused by consuming poisonous shell fishes. The shell fish become toxic due to contamination by dinoflagellates that secrete harmful toxins such as cyanides.

Paralytic shellfish poisoning leads to blockage of sodium channel resulting in paralysis of alimentary canal and respiratory muscles in severe case leading to death of the person
