Which structure in plants allowed the first land plants to survive out of water?
A. cuticle
B. epidermis
C. guard cell
D. spongy mesophyll
Answer:
A
Explanation:
The structure of plants that allowed the first land plants to survive out of water is known as the cuticle. Thus, the correct option for this question is A.
What were the first plants to live on land?The first plants that were tends to live on land are the Non-vascular plants, which include mosses and liverworts, which were the first-ever land plants. They do not have much of an internal support system but have slightly simpler material for the same tasks.
Early in their history, land plants also evolved a cuticle. The cuticle is the structure that involves a waxy layer on the outer surface of the aerial parts of a plant that helps to prevent water loss. Sometimes cuticle with details of epidermal cell structure is preserved in fossil plants.
Guard cells play an important role in the opening and closing of the stomata. While epidermis is the outer cell which prevent the whole plant form injury.
Therefore, the structure of plants that allowed the first land plants to survive out of water is known as the cuticle. Thus, the correct option for this question is A.

Can you use the vocab to create your own sentences to compare and contrast prokaryotic cells with eukaryotic cells? If you need more space, you can attach an additional sheet of paper.
Answer:
True nucleus and organelles.
Explanation:
The main difference between Prokaryotic cells and Eukaryotic Cells are given below.
Prokaryotic cells have no true nucleus while Eukaryotic Cells have true nucleus. true nucleus means that membrane is surrounded the nucleus which clearly show the nucleus. Prokaryotic cells have no organelles while eukaryotic cells have organelles which perform specific function in the cell. these organelles are plasma membrane, ribosome, mitochondria, vacuoles, cytoskeleton, plastids and endoplasmic reticulum.
True nucleus and organelles.
What is the difference between prokaryotes and eukaryotes?
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.

Prophase - nuclear membrane breakdown, chromatin turn to chromosomes and spindle fibers appears.
Metaphase - nuclear membrane completely gone, chromosomes line up along the middle and spindle fibers joins pole to centromere.
Prophase - spindle fibers contract and double stranded chromosomes pulled apart to either poles.
Telophase - nuclear membrane forms, two cells separate, spindle fibers breakdown and chromosomes lengthen and turn to chromatin.

A scientist plans to find out the cause of decrease in bird population in a location. He interviews 50 people who work in the local oil mine and 45 of them believe that the mine does not affect the birds. The scientist concludes that 90 percent of people in the location believe that the local oil mine does not cause decrease in bird population. Why is the scientist's conclusion most likely unreliable? the source of information could be biased the investigation is done by only one person bird population cannot be measured accurately the results of the investigation cannot be repeated
Answer:
The scientist is unreliable since it was supposed to be collecting data on why the birds are dying not why people think they are dying. Also the data would be very biased because he is asking people if they think they are contributing to the problem.
Answer:
A: The source of information could be biased

different organisms can display similar anatomical traits. for example, cats and dogs both have four limbs. why do these different animals have similar anatomical arrangements?
different organisms can display similar anatomical traits because they share common ancestral origin
Since Darwin's time, the study of comparative anatomy has mostly focused on bodily traits that are homologous, or those that, regardless of their current function, may be found in other species and share the same evolutionary ancestry. Such structures may have totally diverse appearances and serve distinct functions, yet they nonetheless share a common structure with an animal that was their ancestor. For instance, the forelimbs of humans, birds, crocodiles, bats, dolphins, and rodents have all undergone various evolutionary modifications to serve various purposes, but they can all be linked back to the fins of crossopterygian fishes, where that fundamental arrangement of bones initially developed. similar structures ,in this way they share common traits
