Answer:
His cell observations have no indication of the nucleus and other organelles found in most living cells, he made use of a microscope containing improved lenses.
Explanation:
None
The correct answer is <em>epithelial tissue.
</em>
There are different types of epithelial tissue depending on the type of cells its made of: squamous, columnar, and cuboidal. It can also be divided into simple and stratified depending on the number of layers. Functions of epithelial cells are wide such as secretion, absorption, protection..
Oxygen molecules are too small and glucose molecules are quite large than oxygen. So they can't passively disuse inside a cell.
Option C
<h3><u>Explanation:</u></h3>
Glucose molecules are large molecules with a molecular formula of C₆H₁₂O₆ These molecules need special protein channels or transporters called Glucose Transporters or GLUT to make them way through the cell membranes. While smaller molecules like oxygen, carbon dioxide, smaller polar molecules like <em>water</em> or even fat soluble molecules like chloroform and benzene do pass through the membranes easily by means of passive diffusion.
The oxygen molecules are needed inside a human cell for aerobic respiration and glucose molecules are needed because of a respiratory substrate. So Glucose needs receptors and transporters to pass through the membranes.
<span>1. D dripstone produced by buildup of minerals precipitated from groundwater.
Water drips down from, for example, the roof of a cave and slowly leaves behind mineral deposits which form a shape similar to an icicle
2. D running water cuts small channels into a slope
Rill erosion is formed by soil removal from small streams of running water. They form based on how the water falls down a slope and tend to migrate to already depressed or softer areas of soil.</span>
Answer: C. 100
Explanation:
In the energy pyramid, 1 secondary consumer to 10 primary consumer and in this question, the herbivorous animals are the primary consumer and the lion the secondary consumer.
Thus 1 lion to 10 herbivores
x lion to 1000 herbivores
X = 1000/10 = 100
