A female mouse is trying to decide if she will leave her natal nest to reproduce alone. If she leaves, she will be able to produce 45 offspring whereas she would only have 7 reproductive units if she stayed. But if she stays, she will help her mother produce 175 offspring vs the 85 she could produce without her. Should she stay

Answers

Answer:

142 is the answer whe you add 45 7 and 85

A female mouse is trying to decide if she will leave her natal nest to reproduce alone. She will produce 142 offspring.

What is reproduction?

Reproduction is the production of offspring. There are two main forms: sexual and asexual reproduction. In sexual reproduction, an organism combines the genetic information from each of its parents and is genetically unique.

In asexual reproduction, one parent copies itself to form a genetically identical offspring. Sea turtles are an example of an animal that reproduces sexually, a volvox (green algae) is an example of an organism that reproduces asexually, and a brittle star can reproduce in either way.

Reproduction is the process by which new organisms (offsprings) are produced from organisms of the same kind.

Therefore, A female mouse is trying to decide if she will leave her natal nest to reproduce alone. She will produce 142 offspring.

Research and produce a summary about the history of the microscope.

Answers

Microscopes have been used for centuries in order to see specimen scientists cannot see with their unaided eye. Antón VanLeeonhoeuk is given credit for designing the first lenses for microscopes in the 16th century. He looked at “animacules” which we would now call bacteria and protists. Robert Hooke first coined the term cell, as he looked at cork and thought it looked like cells that monks slept in. Improvements were made in the following centuries, and Ernest Leintz in the 1800s creates a way to have differing magnification lenses on one microscope. Continuing into the 1900s and 2000s there are now electron scanning microscopes, ultraviolet microscopes, atomic force microscopes, and electron tunneling microscopes—all which allow scientists to have better resolution and to see smaller and smaller things. Microscope technology will continue to improve as scientists discover more ways to magnify the microscopic world.

e: A voltage change occurs in the postsynaptic cell.

Answers

Answer: hi im brain bot

im not sure i know this one im stumped

Explanation:

The event occurs as nerve impulse reaches the synaptic knob, neurotransmitter molecules diffuse across the synaptic cleft. These molecules bind to receptors in the postsynaptic cell and voltage change occurs in the postsynaptic cell. A nerve impulse begins in the postsynaptic cell. The correct option is C.

What is synaptic transmission?

The metabolic pathway by which a neuron interacts with a target cell across a synapse is known as synaptic transmission.

Chemical synaptic transmission is characterized by the release of a neurotransmitter from the presynaptic neuron and the binding of the neurotransmitter to specific post-synaptic receptors.

Synaptic transmission is the process by which a nerve impulse (action potential) travels from the presynaptic neuron to the post-synaptic neuron across the synaptic gap. An action potential is an electrical impulse that travels down the axon of a neuron.

As the nerve impulse arrives at the synaptic knob, neurotransmitter molecules diffuse across the synaptic cleft. These molecules bind to receptors in the postsynaptic cell, causing voltage changes in the cell. and finally nerve impulse begins in the postsynaptic cell.

Thus, the correct option is C.

Your question seems incomplete, the probable complete question is attached below:


Energy pyhamids, otherwise known as trophic level diagrams, are used to represent the flow of
energy through an ecosystem. An organisms trophic level indicates the organism's position in
the sequence of energy transfers. The bottom, or base, of an energy pyramid is a position
always held by the producers and represents (by far) the largest percentage of biomass for
the food web. The need for such a large biomass of producers is to support the energy
needs for all the organisms at higher trophic levels. Draw and label an energy pyramid for the
following 1 hectare of farmland:
• 30,000,000 MJ of Sunlight (solar energy) reaches ground level during a 150-day growing
season
• 52,164 MJ of energy is stored in the soybeans grown on the hectare of land
1,645 MJ of energy is stored in edible beef by cattlewho eat the soybeans

Answers

From the total energy that reaches the ground, 1% is used by producers. The energy transference in the trophic web follows the 10% rule, in which each level uses 10% of the energy stored by the anterior level.

---------------------------------------

Only 1% of the total solar energy that reaches the ground is used by producers, who occupy the first trophic level.

From this input of solar energy, it begins a unidirectional energy flow through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is finally dissipated in the environment.  

At each trophic level, it occurs an energy transfer from one level to the next, with only 10% being usable in each of them. This assessment is called "The 10% rule".

This is, as a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time.

The progressive reduction of energy determines the number of trophic levels (4 or 5).  

If 30,000,000 MJ of Sunlight (solar energy) reaches ground, then only 30,000 MJ can be absorbed by primary producers.

5,216.4 MJ from 52,164 MJ of energy stored in the soybeans, are used by cattle.

 

1,645 MJ of energy is stored in edible beef by cattle who eat the soybeans.

164.5 MJ of this energy is tranferred to the following trophic level.

The primary purpose of the ______ circuit is for the blood to release carbon dioxide and pick up oxygen.

Answers

Answer:

Explanation:

The  primary purpose of the  systemic  circuit is for blood to release carbon dioxide and pick up oxygen

The primary purpose of the pulmonary circuit is for the blood to release carbon dioxide and pick up oxygen.

What is pulmonary system?

It consists of your blood vessels, lungs, and airways. The respiratory system also includes the muscles that propel your lungs.

Together, these components help the body circulate oxygen and eliminate waste gases like carbon dioxide.

The respiratory system makes it possible for the body to take in oxygen and expel carbon dioxide.

The nose and mouth are the beginning of the respiratory system, which continues through the airways and lungs.

The pulmonary circulation serves a variety of crucial purposes. Its main job is to exchange gases across the alveolar membrane.

This ultimately results in oxygenated blood being delivered to the rest of the body and carbon dioxide being removed from the bloodstream.

Thus, the pulmonary circuit's main function is to allow the blood to absorb oxygen and release carbon dioxide.
