How do protists, fungi, or plants potentially benefit or harm us? You should be able to find a pro and a con for each type of or
IgorLugansk [536]

Here are some potential benefits and harms of protists, fungi and plants:

  1. Protists:

Benefits: Some photosynthetic protists are one of the most important food source for many sea animals like sharks- the big giant aquatic creatures. They are responsible for producing 40% of the food that other organisms consume. Several little sea organisms like shrimp and larval crabs depend on protists for their food. Humans also harvest protests for food since they hold primary position in the food chain.

Harms: Like any other organisms, protists can also harm, especially to humans. There is a specific group of protists called animal-like protists that act as a parasite and harm human being.  

For example: a fatal disease malaria is caused by a protist called plasmodium that is transmitted to human through a mosquito bite. Malaria can cause symptoms like headaches, vomiting and fever, and in severe cases can lead to the death of individual.

     2. Fungi:

Benefits: Some fungi are very useful for humans like mushrooms. They are part of our delicious cuisines and add flavor and aroma to the food. Yeast is a fungi that is used to make bread and soya sauce. They are also source of useful compounds that scientists used to treat bacterial and viral infections.

Harms: Fungi can be really harmful to humans as well. They cause several diseases in humans and crops such as, Rusts and smuts on farm crops and orchards, Athletes foot and oral thrush in humans.

  3. Plants

Benefits: It won’t be wrong to say that we owe our existence to plants. They are not only important for humans but all other living organisms. Humans cannot survive more than few minutes without the supply for oxygen. Plants release the oxygen that humans use to breathe and survive.

Harms: Most of the plants are useful and just useful to us. They don’t eat us, run after us or kill us. However, some plants are so dangerous that only standing near them can cause harmful effects on human health. For example, the Manchineel tree is found throughout the Carribean and America, getting splash of its run off or inhaling its dust can quickly cause itching and swelling all over the skin. If you just touch its skin, your body will experience rashes quickly!

Hope it helps!

Acetic acid and ethanol react to form ethyl acetate and water, like this: (aq)(aq)(aq)(l) Imagine of are removed from a flask co
ehidna [41]

Answer:

Greater than zero, and equal to the rate of the reverse reaction

Explanation:

this is an incomplete question in the first place, i saw the complete format online hence the answer am giving here.

Before any C2H5CO2CH3 is or was removed, the system is said to be in equilibrium.

This means that the rate of consumption of reactants and rate of generation of products are greater than zero and are equal, that means that both the forward and backward reactions are occurs at these rate.

A gene that affects hair length in dogs has two alleles. The allele for short hair (L) is dominant
Lelechka [254]

Answer:

This question lacks options, the options are:

A. Only recessive alleles are inherited from homozygous parents.

B. Dominant alleles grow weaker as they are passed from parents to offspring.

C. Only the parent with a dominant allele can pass that allele to offspring in sexual reproduction.

D. A heterozygous parent has an equal chance of passing either the dominant allele or the recessive allele to offspring.

The answer is D

Explanation:

This question involves a single gene coding for hair length in dogs. The allele for short hair (S) is dominant over the allele for long hair (s). This means that allele 'S' will always mask the phenotypic expression of allele 's' in a heterozygous state.

According to the question, two heterozygous dogs (Ss) were crossed to produce 6 shortt-haired offsprings and 2 long-haired offsprings. An heterozygous organism is that which contains two different alleles for a particular gene i.e. a combination of dominant and recessive alleles.

Based on this, during meiosis or gamete formation, an heterozygous dog (Ss) will produce gametes with the short hair allele (S) and long hair allele (s) in equal proportion i.e. 50-50. When the two gametes containing the recessive alleles (s) produced by each heterozygous parent fuses, an offspring with a recessive phenotype (long hair, ss) is produced.

Hence, a long-hair

phenotype can appear in the offspring of two short-haired dogs because a heterozygous parent has equal chance of passing either the dominant or recessive allele to the offspring.

DNA is copied in a process called:
d1i1m1o1n [39]

Answer: Transcription

Explanation:

Transcription is the process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis. ... The pre-messenger RNA is then "edited" to produce the desired mRNA molecule in a process called RNA splicing.
