Colostrum, which is rich in protein, micronutrients, and antibodies, is replaced by mature milk in about

Biology
1 answer:
Allisa [31]4 years ago

<span>About 2 weeks. Since the species isn't mentioned, I will assume human. Definitions Colostrum: This is the fluid expressed by the breasts just prior to and for a few days after giving birth. It contains a much higher concentration of nutrients in an easier to digest form than regular breast milk. This type of breast milk will be produced for 2 to 4 days after giving birth. Transitional Milk: This is a thick creamy milk that contains more fat, lactose, vitamins and calories than colostrum. It starts within 4 days of giving birth and lasts approximately 2 weeks. Mature Milk: This is a thinner milk that's about 90% water and 10% nutrients. It starts about 2 weeks after giving birth. So the answer is about 2 weeks.</span>

With regard to the process of neural transmission, a refractory period refers to a time interval in which:
frutty [35]
<h3><u>Answer;</u></h3>

d. a neuron recharges before it can fire again.

<h3><u>Explanation;</u></h3>
  • <em><u>Refractory periods are a short phase in time following an action potential where another action potential cannot be generated. </u></em>
  • <em><u>It is the period immediately following the transmission of an impulse in nerve or muscle, in which a neuron or muscle cell regains its ability to transmit another impulse. </u></em>
  • There are two types of refractory period, that is the absolute refractory period and the relative refractory period. Absolute refractory period is the first part of a refractory period during which, the neuron will not fire again no matter how great the stimulation and this only lasts for a short time.
  • Relative refractory period occurs when a stronger than usual stimulus is required to trigger the action potential before the neuron returns to resting state.

What benefit could plastic made by plants have over traditional plastic?
Mrac [35]

1) Since plants are a renewable resource and oil is not, we will eventually run out of the materials needed to make traditional plastic, but we will not run out of what we need to make plant-based plastic.

2) Farming has a much lower carbon footprint than oil extraction and processing does.

3) Plant-based plastic can be biodegradable.

Nuclear power has come under higher scrutiny in recent years. Which statement would make the strongest for the use of nuclear po
Tamiku [17]

The Answer is A) Nuclear power generates large amounts of power limited to projection of greenhouse gases.

I believe this is the answer. As per the reports in 1998, it has been calculated the emission of the greenhouse gas has reduced for nearly half due to the popularity in the use of nuclear power. Nuclear energy by far has the lowest impact on the environment since it does not releases any gases like carbon dioxide, methane which are largely responsible for greenhouse effect. There is no adverse effect on water, land or any habitats due to the use of it. Though some greenhouse gases are released while transporting fuel or extracting energy from uranium.

Have a great day. Keep asking questions!
