What are prokaryptes?Any organism that lacks internal membranes, which prevents the formation of a distinct nucleus and other organelles, is referred to as a prokaryote (also written procaryote). The most well-known prokaryotic species are bacteria. Prokaryotes are different from eukaryotes because they don't have internal walls.
Separate prokaryotic kingdoms with purportedly distinct evolutionary histories are called bacteria or eubacteria and archaebacteria or archaea.

cuáles son las características adaptativas que favorecen la sobrevivencia de los pingüinos?
Answer:
Los pingüinos tienen una cola corta y rígida. Pueden inclinarse hacia atrás y mantener el equilibrio sobre los talones y la cola. Esto reduce la pérdida de calor de los pies al suelo. El color del cuerpo de un pingüino ayuda a camuflarlo cuando nada.
Explanation:
Penguins have a short stiff tail. They can lean backwards and balance on their heels and their tail. This reduces heat loss from their feet to the ground. The color of a penguin's body helps to camouflage it when it is swimming.

Please answer correctly
Answer:
A) Identify the Dependent and Independent variables
The Independent variable is Temperature.
The Dependent variable is the seeds. The dependent variable is the variable that is being studied.
B) Calculate the average height of the seedlings in tube C.
To find the average, you must add up all of the heights and divide by the number of seedlings.
3.4 + 4.5 + 2.5 + 3.7 + 2.8 + 4.4 + 4.3 + 2.9 + 2.1 + 3.7 = 34.3
34.3 ÷ 10 = 3.43 cm
C) Conclusion
The seedlings in tube C grew much taller than the seedlings in tubes A and B.
This means that seedlings germinate better in warmer temperatures.
D) Why does Temperature affect Germination?
The temperature of the climate affects the dampness of the cotton wool. Moisture is key to germinating seeds. Seeds like a moist but not soggy environment caused by the correct temperature.
E) How could the experiment be better controlled?
The light levels in this experiment varied, but were not accounted for in the calculations.
It would have been better to keep them all under the same amount of light in order to keep the experiment accurate.

Evan's playroom is 4 m by 3 m. The area of the room is:
o 7 m
07 m2
O 12 m
O 12 m2
Answer:
12 m^2
Explanation:
Area = length * width
A = 4m * 3m
A = 12 m^2
(Area is measured in square units)
Answer:
D. 12 m2
Explanation:
To do this problem, you need to find the area. To find the area of a rectangle, you multiply length x width. In this scenario:
4 x 3 = 12.
So, we know that the first two options are incorrect. Next, we have to look at the unit of measurement that we are needed to imply. In this case, we are using meters, which we need to square. Therefore, the answer is 12 m2.

The number of white-tailed deer in certain areas of Long Island, NY has increased significantly. Homeowners and farmers have put up tall fencing to protect their gardens and crops from the deer. One reason why the white tailed-deer might have increased significantly in certain areas of Long Island is * 3 points A the lack of natural predators B an increase in deer pathogens C a shortage of biotic resources needed by the deer D that carrying capacity has no effect on deer populations
Answer:
A. the lack of natural predators
Explanation:
The white-tailed deer inhabits a wide variety of environments. The species characterizes by its adaptation to different conditions, especially in contact with human beings and their activities.
Due to human action and the change in the environment, populations of white-tailed deer have expanded to Canada. Due to its adaptability capability, the deer have reproduced more than expected in some regions, up to the point of being detrimental for people.
In fact, In the United States and Canada, the overabundance of the species has brought consequences to people, such as plagues, accidents, diseases, material loss, among others.
Human action modified the deer habitat, but other species were affected too. It is the case of wolves or pumas, natural predators of the white-tailed deer. The natural habitats of these species have been destroyed, and they have been summited to extensive hunting for years. Habitat reduction and hunting drove these species to disappear.
One of the principal reasons for deer overpopulation is the absence of predators. Under natural conditions, pumas and wolves keep deer population growth under control. However, once these species were eliminated, the white-tailed deer was not affected by predation pressures anymore
The absence of natural predators and the adaptation capability to different environments and border effects made it possible for the white-tailed deer population to overgrowth.

A.

Did you know: There are over 1,400 species of bats worldwide. Bats can be found on nearly every part of the planet except in extreme deserts and polar regions. The difference in size and shape are equally impressive. Bats range in size from the Kitti’s hog-nosed bat (also called the Bumblebee Bat) that weighs less than a penny -- making it the world’s smallest mammal -- to the flying foxes, which can have a wingspan of up to 6 feet. The U.S. and Canada are home to about 45 species of bats and additional species are found in the U.S. territories in the Pacific and Caribbean.
