what is the principle drawback of broad-spectrum pesticides?
Answers
The primary disadvantage of broad-spectrum pesticides is their potential to destroy non-target organisms.
The primary disadvantage of broad-spectrum pesticides is their potential to destroy non-target organisms. Broad-spectrum pesticides are intended to kill a wide variety of pests, but they also kill helpful insects such as bees, birds, and butterflies, as well as animals like fish, amphibians, and mammals that live in waterways or eat contaminated prey. As a result, broad-spectrum pesticides have a greater environmental effect than more specific alternatives. These toxins also have a negative impact on human health, posing potential dangers to people who work with pesticides, consume tainted food, or breathe contaminated air.The danger of pesticides has been recognized by scientists, environmentalists, and the public at large. Scientists, environmentalists, and the public at large have all recognized the danger of pesticides. To combat this, new types of pesticides are being developed that are less hazardous to non-target organisms and the ecosystem as a whole, such as selective pesticides that target only certain species of pests while leaving other species unharmed. Integrated pest management (IPM), which aims to minimize pesticide use while still managing pest populations, is another environmentally sustainable alternative to broad-spectrum pesticides.

What are Tectonic Plates made of and what do they do?
Answers
Answer:
They move
Explanation:
Answer:
A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere.Plate tectonics move because they are carried along by convection currents in the upper mantle of the planet (the mantle is a slowly flowing layer of rock just below Earth's crust). Hot rock just below the surface rises and when it cools and gets heavy, it sinks again.

Explanation:
a paleontology student plans to compare the genomes of fossilized marine organisms from africa and north america to identify how long ago they had a common ancestor. like most old fossils, the tissue and shell of the organism have been replaced by quartz and calcium rock. what faulty reasoning will the student's research advisor most likely point out? (2 points) the ancient marine organisms most likely lack a common ancestor shallow enough in the ocean to be reached. the genomes would have suffered mutations after the organisms died due to environmental factors, so they will yield incorrect ages. the rock that makes up the fossils replaced the organisms' tissue and genetic material, so their genomes can't be extracted. the fossils are on two different continents, so a common ancestor will not exist.
Answers
The faulty reasoning that the research advisor is most likely to point out is A: "The ancient marine organisms most likely lack a common ancestor shallow enough in the ocean to be reached," and D: "The fossils are on two different continents, so a common ancestor will not exist."
The research advisor is likely to point out that the assumption of the ancient marine organisms lacking a common ancestor shallow enough in the ocean to be reached is faulty reasoning. This is because organisms in the ocean, regardless of their depth, still share common ancestry and can be compared genetically to determine their evolutionary relationships. The depth of the ocean does not prevent the existence of a common ancestor.
Similarly, the assumption that a common ancestor will not exist simply because the fossils are on two different continents is also faulty. Evolutionary relationships are not limited to geographic proximity. Organisms can migrate, disperse, and evolve over time, leading to the possibility of a common ancestor existing even between organisms on different continents.

State 8 differences between sexual and asexual reproduction
Answers
➩Reproduction:
Reproduction is a process by which living organism produce new organisms of same species (of their own kind)
Reproduction is neccessary for the survival and increase in population of species. It ensures continuity of various species on earth. In simple words if organisms will not reproduce there population will decrease and species will become extinct.
➽Mainly there are two types of Reproduction
(i) Sexual reproduction
(ii) Asexual reproduction
➩Sexual Reproduction
→ In sexual reproduction two individuals are involved to produce a new individual (male and female)
→The entire reproduction process takes longer time and more energy.
→ Population increases relatively slowly.
→ It involves more variations.
→ Species can adapt to an environment which changes.
→This leads to evolution.

Answers
After food is digested, a carbohydrate called glucose will leave the bloodstream through a capillary wall.
Glucose is a simple sugar. It is a primary source of energy for cells. It is absorbed from the digestive system into the bloodstream and then transported to various tissues and cells throughout the body.
Through the process of cellular respiration, glucose is used by cells to produce ATP. ATP is the energy currency of the cell. Excess glucose in the bloodstream can be stored as glycogen in the liver and muscles or converted into fat for long-term energy storage.

They are characterized by their simple cellular structure, with genetic material (DNA) floating freely in the cytoplasm rather than being enclosed within a nucleus. Prokaryotes include bacteria and archaea, which are the oldest and most abundant forms of life on Earth.
These microorganisms exhibit diverse shapes and sizes and can be found in various environments, including soil, water, and even within the human body.
