What does it mean to say science is a systematic process
What is a plant nucleus
Answer:
All plant cells contain a nucleus, a structure that stores DNA and acts as a cell's command center. It is surrounded by the nuclear envelope and is filled with nucleoplasm. ... DNA is copied during DNA replication for new cells, as well as copied to RNA to make proteins in the nucleus.

make proteins.
Answer: grow and reproduce
Explanation:
Scientists have been studying the size of three populations in a river in Ireland. In this ecosystem, pike (a type of big fish), and perch eat snails. The data showed that all three populations were stable. Then the snail population increased suddenly. What will likely happen to the size of the perch population as a result? The size of the perch population will...
Options:
A. Stay the same. The size of it's consumer population did not change, so the number of deaths in the perch population did not change. There will be the same number of births and deaths in the perch population.
B. Decrease. The larger snail population will take more energy storage molecules from the ecosystem, leaving fewer available for the perch population. This will lead to more deaths than births in the perch population.
C. Increase. The larger snail population will provide more energy storage molecules for the perch population, so they will reproduce more. This will lead to more births than deaths in the perch population.
D. Increase. An increase in any population within an ecosystem will lead to an increase in the sizes of all other populations in the ecosystem.
Answer:
C. Increase. The larger snail population will provide more energy storage molecules for the perch population, so they will reproduce more. This will lead to more births than deaths in the perch population.
Explanation:
Comb jellies are:____.
A. Bilaterally symmetrical.
B. Similar to a cnidarian polyp.
C. Distinguished by eight bands of cilia.
D. Colonial animals.
E. Carnivores that use nematocysts to capture prey.
Answer:
C. Distinguished by eight bands of cilia.
Explanation:
Ctenophora, also known as comb jellies, represents a phylum of transparent, mostly pelagic, invertebrate marine animals that live around the world. This group characterized by eight rows of cilia (singular cilium) that are used for locomotion. Cilia are organelles and/or structures that extend from the surface of eukaryotic cells, which can be used to move the surrounding fluid, resulting in cell movement. This phylum is divided into two classes: Tentaculata (with tentacles) and Nuda (without tentacles).

When curare, a neuromuscular poison, is dropped onto an isolated muscle-nerve preparation in a laboratory, the muscle does not contract when the nerve is stimulated, even though neurotransmitter is released from the nerve cell. Why does this happen
Answer:
Explanation:
Whenever the nerve terminal's action potential depolarizes, calcium enters the cell through the channels. Calcium allows acetylcholine (ACh) to be released more easily. These ACh molecules subsequently circulate into the synaptic cleft and attach to the motor end-plate of the nicotinic cholinergic receptors. Acetylcholine molecules connect to nicotine ion-channel receptors present on cell membrane the of muscle cells, enabling the ion channels to open. Calcium ions then enter the muscle cell, kicking off a series of events that eventually result in muscular contraction.
Curare is a kind of neuromuscular relaxant blocker that is non-depolarized in nature. Nondepolarizing muscle relaxants work as competitive agonists, binding to ACh receptors but failing to activate ion channels. As a result, they inhibit ACh from bonding, preventing the development of endplate potentials and inducing muscle paralysis.

Describe sea turtle populations during the late 1400’s
Answer:
6.5 million sea turtles
Recent estimates show us that there are nearly 6.5 million sea turtles left in the wild with very different numbers for each species, e.g. population estimates for the critically endangered hawksbill turtle range from 83,000 to possibly only 57,000 individuals left worldwide.
