which event during the evolution of land plants probably made the synthesis of secondary compounds most beneficial?

Answers

Answer 1

The rise of herbivory during the evolution of land plants probably made the synthesis of secondary compounds most beneficial.

The emergence of herbivory in the Carboniferous was a watershed moment in the development of terrestrial ecosystems. Not only did it give animals greater ecological diversity, but it also increased their influence on the development of land plants. As allelopathic agents (allelochemicals that influence competition among plant species), attractants (pigments or scents) for pollinators and seed-dispersing animals, and as protection against herbivory and microbial infection, secondary compounds have significant adaptive significance. It appears that ecological interactions with other species are the primary area in which these secondary compounds are crucial.

A. Landfills solved pollution problems caused by waste disposal.
B. Wastewater from cities no longer carries toxic chemicals into waterways.
C. Laws regulating waste disposal have put an end to pollution problems caused by waste.
D. Much of the pollution in our environment is a byproduct of inadequate waste disposal.

Answers

Answer:

D

Explanation:

all the others are false

Much of the pollution in our environment is a byproduct of inadequate waste disposal, hence option D is correct.  

What are the problems of waste disposal?

There are some problems caused by solid waste disposal include: finding suitable landfill locations, groundwater pollution, and soil pollution.

Landfills have not solved pollution problems caused by waste disposal, because it creates soil pollution in the area where waste is disposed of, which decreases the fertility of the soil.

Wastewater from cities carries toxic chemicals into waterways, which is the major cause of water pollution in that area. There are some laws that regulate pollution, but not all the person follows them.

Therefore, waste disposal is the major factor of pollution.

Longitudinal waves are waves that transfer energy parallel to the direction of wave motion. Transverse waves are waves that transfer energy perpendicular to the direction of wave motion.

Answers

Answer:

Longitudinal waves are waves that transfer energy parallel to the direction of wave motion.

Transverse waves are waves that transfer energy perpendicular to the direction of wave motion.

Explanation:

First of all, transverse waves are not mechanical waves at all. Longitudinal waves are mechanical waves.

Longitudinal waves are waves that transfer energy parallel to the direction of wave motion. A typical example of longitudinal waves is wave on a spiral spring.

Transverse waves are waves that transfer energy perpendicular to the direction of wave motion. A typical example of a transverse wave is light wave and other electromagnetic waves.

Answers

Answer:

The right temporal lobe

Explanation:

The cerebral cortex of the brain has two sections known as hemispheres, and each hemisphere can be divided into four lobes: frontal, parietal, temporal and occipital. Alzheimer's disease is the most common cause of dementia, which is characterized by the damage of the temporal lobe. Alzheimer’s disease usually initiates in the hippocampus, which is a structure inside each temporal lobe. The temporal lobes are involved in different neuronal functions: object recognition, face recognition, perception, memory, language, emotions, etc. The right temporal lobe is mainly involved in processing visual information (i.e., face recognition, object recognition, familiar recognition).

In Ribonucleic acid (RNA) we have 5 carbon ribose sugar, phosphate group and nitrogenous bases which are purine and pyrimidine. Purine consist of Adenine and guanine while pyrimidine compose of Cytosine and Uracil where thymine in DNA is replaced by Uracil in RNA. This makes Thymine a components of DNA not RNA.

A. Recessive
B. Nucleus
C. Dominant
D. Eukaryotic

Answers

Answer:

A. Recessive

Explanation:

Only answers A and C can be used to describe an allele, so B and D can't be it. If the allele was dominant, only one copy would be necessary for the phenotype to be expressed (ex. heterzygous green peas are still green, even though they carry a yellow allele). Therefore, since 2 copies are present for this phenotype, it must be recessive.
