Answer:
The limitations that nerve impulses have are
Explanation:
1). The impulses can move only in one direction.This is because the nerves are structured to allow unidirectional flow.
2). The electrical impulses are quite short acting. The message is only sent in the presence of the stimulus.

Mecanismo de defensa de algunos animales que consiste en un aislamiento en cuevas o madrigueras durante los periodos desfavorables del año a Madriguera es verdadero o falso
Answer:
Responder:
CIERTO.
Explicación:
Este es un ejemplo de adaptaciones conductuales conocidas como adaptaciones anti-depredadoras. Esto es principalmente importante en áreas donde hay poca vegetación. Los búhos de madriguera, las tortugas que viven en los desiertos y las suricatas son ejemplos. Estos animales se encuentran en regiones de baja vegetación. Por lo tanto, no están protegidos de los depredadores. Por lo tanto, cavan profundo bajo tierra para escapar del depredador.
Además, debido a que estas regiones son principalmente áridas, los animales necesitan escapar de la alta temperatura y, por lo tanto, conservar el agua.
Which example is most likely made from both metals and gemstones?
Necklace
Soda can
Widow frame
Kitchen utensils
Answer:
A. necklace
Explanation:
Necklace is most likely made from both metals and gemstones.
What is necklace?A necklace might be a straightforward chain made of gold or silver, a string of beads or diamonds, or a pendant suspended from a rope. It qualifies as a necklace as long as it is worn around the neck.
Unless you are a professional or amateur geologist—or perhaps you earned a merit badge studying them as a scout—you probably won't be able to explain the differences between these four hard natural materials: minerals, rocks, gemstones, and crystals.
The different types of necklace are chocker, Matinee and opera. Long and functional, opera length necklaces. The necklace should hang below the bust when worn as a single strand.
Therefore, Necklace is most likely made from both metals and gemstones.

Which phylum is a group of miscellaneous fungi that don’t fit into the other three categories? Zygomycotes Deuteromycotes Ascomycotes Basidiomycotes
Answer:
Deuteromycotes
Explanation:
Kingdom Fungi consist of eukaryotic organisms grouped into 3 phyla, with one group that doesn't fit into any of the grouped three. Each group of fungi were classified into phylum based on their reproductive life cycle. The three phyla are Zygomycotes, Ascomycotes, Basidiomycotes.
Zygomycotes produce their spores by meiosis in a structure called Zygosporangium. Ascomycotes produce their spores via meiosis in ascus (sac-like). Basidiomycotes produce their own spores via meiosis in club-like basidium.
However, a fourth group exists that has no known sexual reproductive structure (meiospores), instead it is known to reproduce asexually via mitospores. This group is called DEUTEROMYCOTES or commonly known as FUNGI IMPERFECTI. It is a group of miscellaneous fungi that doesn't fit into the classification basis of the other three phyla.
Do the populations change very much, or are they in equilibrium? Explain.
Answer:
They are in equilibrium
Explanation:
This is because they compete for resources such as food,water,mates e.t.c. hence only the fittest survive.Also the organisms that die are replaced by newborn ones.An ecosystem can support a specific number of organisms without depleting its resources.

A pair of mice are bred several times generating the following data table. What are the most likely genotypes of the parents?
Answer:
This question lacks options, the options are:
A) FF and ff
B) FF and Ff
C) Ff and Ff
D) Ff and ff
The answer is D (Ff and ff for parent 1 and 2 respectively)
Explanation:
This question depicts a single gene coding for fur colour in mice. The gene controls two traits, black fur and white fur, encoded by alleles F and f respectively.
According to the question, a pair of mice has been bred several times to generate the same data of 22 black fur and 23 white fur mice. Based on this data, it shows that the phenotypic ratio of black to white mice is 1:1.
To get a 1:1 phenotypic ratio of black fur offspring to white fur offspring, the parents mice must have genotypes Ff (heterozygous) and ff (same recessive alleles).
In a cross between parents Ff × ff (see punnet square), offsprings with the following genotypes will be produced: Ff, Ff, ff and ff. Ff is black furred while ff is white furred.
Ff (2) : ff (2) is equivalent to Ff (1) : ff (1).
Hence, a data of 22 black mice and 23 white mice which represents a 1:1 ratio will only be produced by parents mice with genotypes: Ff and ff.

Ramu wants to practice crop rotation in his field. Suggest a Rabi crop and a Kharif crop, which will replenish his field with nitrogen. Which crop replenishes nitrogen and why?
Answer:
Explanation:
is a practice that involves the growing of different type of crop on the same piece of land. It is often practices by subsistence farming where the land space is not to big to accommodate all the crops to be grown separately.
Nitrogen are been replenished into the soil by leguminous crops. This is because they have root nodules which contains Nitrogen and it help fixes it back into the soil with the help of bacteria such as Azotobacter, nitrogen fixing bacteria. This bacteria acts on the nodules to help break down the Nitrogen into a form that can be useful by plants.
Example of kharif Crop is pea which are leguminous and can fix nitrogen back into the soil, maize, rice
Rabi example is wheat and barley.

Which structural organizations are present in all proteins? A- Primary and Secondary B- Secondary and Tertiary C- Tertiary and Quaternary D- Primary and Tertiary
Answer:
Option A
Explanation:
The primary and Secondary structure are essential and present in all proteins and also include tertiary.
The primary structure is the amino acid sequence of the protein. This is the basic part of the protein.
The secondary structure are local folded structures that form within a polypeptide as a result of a couple of interactions between atoms of the backbone giving rise to the alpha helix and the beta pleated sheets in protein structures.
How do gambierdiscus toxicus cells move?
Answer:
Some dinoflagellates with benthic habits are related to ciguatera intoxication by fish consumption, especially in tropical areas. In the Mexican Caribbean, ciguatera is relatively common, but only one paper seems to have been published on the subject, and there are very few publicactions on phytoplankton and benthic microalgae. Material collected along the coast of the State of Quintana Roo with phytoplankton net (54 mm) and directly from sediment and epiphytes of macroscopic plants, was searched for toxic and other associated dinoflagellates. Samples were studied by light and scanning electron microscopy. Morphological characters were useful for species identification, but eventually physiological, ecological and molecular characters could also be used. Three species of Gambierdiscus, related to the production of ciguatera toxins, were identified: G. belizeanus, G. toxicus and G. yasumotoi. They are distributed in shallow coastal areas, including coastal lagoons.

The cell cycle describes the processes that take place as a cell Your answer: A.forms new cells. B.absorbs nutrients. C.makes proteins.
Answer:
Choice A
Explanation: This is because the main purpose of the cell cycle is to create new cells for the organism via mitosis or meiosis.
The cell cycle illustrates the procedures, which occurs as a cell produces new cells.
What is cell cycle?It refers to a series of events, which occurs in a cell as it grows and differentiates.
A cell devotes majority of its time in the phase known as interphase, and during this time it develops, divides its chromosomes, and prepares for the division.
After that the cell leaves interphase, and goes through the process of mitosis, and completes the process of division.
It can be said that the prime task of cell division is to produce novel cells.
Thus, the correct answer is option A, that is, forms new cells.

how the surface area and volume of cells affect the rate of exchange of materials in and out of cells in multicellular organisms
Answer:
cells want the highest ratio of suface area to volume, as it makes it most efficient to get materials in and out.
Explanation:
this is why cells are small. if cells were super big, it would like a long time fro materials to travel from one end of the cell to the other. this would lead to a buildup of toxic chemicals and things they want to remove. a large surface area means that there is more space for materials to go in and out.
Answer: When the cell increases in size, the volume increases faster than the surface area, because volume is cubed where surface area is squared. When there is more volume and less surface area, diffusion takes longer and is less effective. ... this is actually why cells divide.

What are some of the consequences of acid rain? Thanku
The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes. The more acid that is introduced to the ecosystem, the more aluminum is released, die of biodiversity in environment and other organism that supports decomposition of material
