Will notices that crickets seem to chirp more frequently at night in June the they do in October he asks himself how do temperature changes affect how often crickets chirp if he were to perform an experiment which if theses statements would be the best hypothesis

Answers

Answer:

This question lacks options; the options are:

A) Crickets are inactive in October.

B) Do crickets like warm weather better than cold weather?

C) Crickets chirp more frequently as temperature increases.

D) Crickets chirp for many reasons, and temperature is probably one reason.

The answer is C

Explanation:

A hypothesis is a testable explanation given to an observed problem. The hypothesis aims at solving or answering a particular question or observation. A hypothesis, which is subject to testing via experimentation, explains how the independent variable affects the dependent variable.

According to this question, Will notices that crickets seem to chirp more frequently at night in June than they do in October. He then asks a scientific question based on this observation that goes thus: how do temperature changes affect how often crickets chirp?

The best hypothesis that explains this scientific question is "Crickets chirp more frequently as temperature increases" because it gives a predictive statement about how a change in temperature (independent variable) affects chirping in crickets (dependent variable).

Which of the following is not true concerning the usage of public land.a. Public land is managed by federal and state agencies.b. Unprotected lands exist inside federal parksc. Public land can be protected or unprotected.d. Wilderness areas and state parks are protected.

Answers

The correct option is this: UNPROTECTED LAND EXIST INSIDE FEDERAL PARKS.

Lands generally belong to three categories of owners, these are federal government, state government and private owners. The lands belonging to the federal and the state governments are considered to be public lands and they are always protected; the lands can not be used for any purpose by anybody unless permission is first obtained from the government. Public lands are typically used for construction of social infrastructures that will benefit all.


Unprotected land exists inside federal parks.

Further Explanation:

Federal lands are the portion of the properties which are owned by the citizens of the United States. These lands are possessed by the federal government. The federal lands are managed by three different agencies  

1. Bureau of land management

2. United states fish and wildlife service  

3. National park service

The maximum federal lands are located in Alaska and Western states. The American citizens own all federal properties , which include national parks, wildlife reserves, and national forests. The American public has the right to excess and enjoys these land areas. American citizens pay a fixed amount as income tax for the preservation and management of public lands. State lands are used to generate revenues by state governments. State lands are not possessed by the American citizens as public lands. The State lands are being sold and managed by state authorities.

With respect to acetylcholine, botox is to nicotine as _____ is to _____.

Answers

Answer:

antagonist to agonist

Explanation:

Glutamate has excitory effect on the nerve fibres in the central nervous system. It is mostly found in synaptic vesicle of nerves terminals in abundance and can be released through exocytosis. The glutamate has special transporters on the plasma membrane that allow it to be transported across neurons.

A drug increases the effect of the neurotransmitter is called an agonist. If it decreases the effect of the neurotransmitter it is called an antagonist. If the neurotransmitter is excitatory like glutamate above, nicotine presence will increase the excitatory effect, and presence of botox will decrease the excitatory effect by inhibit its diffusion across the neurone.

All of the following are true of culture except... a. it is not transmitted across generations b. it provides a blueprint that determines the way we think, feel, and behave in society c. it helps to define who we are d. it influences our knowledge, beliefs and values

Answers

Answer:

All of the following statements about culture are true except for "a. it is not transmitted across generations."

Culture refers to the shared beliefs, values, customs, behaviors, and artifacts that characterize a particular group or society. It is an essential part of human societies and influences various aspects of our lives. Here are the correct statements about culture:

b. Culture provides a blueprint that determines the way we think, feel, and behave in society. It shapes our worldview, influences our perceptions, and guides our actions. For example, cultural norms and values influence how we interact with others, make decisions, and interpret social situations.

c. Culture helps to define who we are. Our cultural background plays a significant role in shaping our identity. It contributes to our sense of belonging, shapes our individual and collective identities, and influences how we perceive ourselves and others.

d. Culture influences our knowledge, beliefs, and values. It provides a framework for understanding the world around us and shapes our understanding of what is right, wrong, important, or valuable. For instance, cultural beliefs may influence our attitudes towards education, religion, family, gender roles, and social issues.

However, statement a. is incorrect. Culture is indeed transmitted across generations. It is passed down from one generation to another through various mechanisms such as socialization, education, storytelling, traditions, and language. Each new generation learns and internalizes the cultural practices and beliefs of their society, contributing to the continuity and preservation of culture over time.

In summary, culture is transmitted across generations and has a profound impact on our thoughts, feelings, behaviors, identity, and values.
