Joint Firs are the plants in which division can live as long as 1500 to 2000 years.
Explain how isolation causes the making of new species?
Answer:
Explanation:
When organisms become isolated the two groups are also not able to reproduce together, so in one group are not necessarily found in the other group. The longer the groups are isolated, the more different they are. They eventually become different species.
3. Meiosis is a process that occurs during cell division that leads to the production of gametes It halves the number of chromosomes that can be passed on to an offspring. It also produces new combinations (variations) of an organism's genetic material Use evidence you obtained from modeling meiosis to show that both statements are true

(40 points) Look at the diagram below. Which animals are most closely related? Which animals are least closely related? Explain your answer.
Answer:
The most closely related are amphibians and reptiles.
The least related are amphibians and mammals
Explanation:
Amphibians broke off from reptiles, birds, and mammals around 260 millions years ago and next up are the reptiles which broke off around 225 million years ago. So they are the most closely related
Mammals are the last to break off, around 200 million years ago. So they are the least related to amphibians.

A plant can have green (G) or yellow (g) leaves. It can also have a long (K) or
short (k) stem. A scientist is preparing a Punnett square for a dihybrid cross
of a plant with a genotype GgKk. What possible gametes can the plant
produce?
O A. GK, Gk, gk, gK
• B. GK, GG, KK, kK
• C. GK, Gk
O D. GK, gk
The possible gametes the plant can produce would be GK, Gk, gK, and gk. The correct option is A.
Gametes formationIn order to determine the possible gametes from the parent with the genotype GgKk, we need to cross the two traits in a monohybrid cross.
Thus: Gg x Kk
GK Gg gK gk
Thus, the possible gametes are GK, Gg, gK, and gk.

It has chloroplasts and vacuoles and moves using a flagellum.
How would you classify the way that it gets energy? Is it an autotroph or heterotroph?
Explain your answer in at least two complete sentences.
An organism that has chloroplasts and vacuoles and moves using a flagellum would be classified as an autotroph.
What is an autotroph?An autotroph is an organism that can generate its own food, which is due to a chemical process called photosynthesis.
Photosynthesis occurs in a specialized organelle called chloroplast that traps sun radiation to convert it into chemical energy.
In conclusion, an organism that has chloroplasts and vacuoles and moves using a flagellum would be classified as an autotroph.

What are the 4 major groups of birds?
Answer:
Strisores — nightjars, frogmouths, and other nocturnal birds, along with diurnal swifts and hummingbirds.
Columbaves — turacos, bustards, cuckoos, pigeons, sandgrouse, and mesites.
Gruiformes — cranes, rails, crakes, Sungrebe, flufftails, and others.
Aequorlitornithes — shorebirds, flamingos, grebes, gulls, tropicbirds, penguins, and other waterbirds.
Explanation:
Answer: The four important group of birds are 1. Game Birds 2. Preying Birds, 3. Perching Birds and 4. Flightless Birds.
Game birds are good runners but they cannot fly long distances. Their wings are short and round, but legs are massive. The beaks are also strongly built. Males are aggressive. One male maintains a group of 3-4 females. Game birds include partridges, pheasants, quail, grouse and pea fowls.
Preying birds are predators. They kill mice and other smaller animals and eat them. They have very strong, hook-like beak. There feet have curved and pointed claw. Their vision is very sharp. Preying birds include vultures, kites eagles and falcons.
Perching birds constitute the largest group of birds. When they sit on a tree, their digit grasp the branch of the tree in such a way that they cannot fall off the branch. Baya, larks, swallow, bulbul, finches, house sparrow, weaver-bird, crow and magpie are some common perching birds.
Flightless birds can run but they cannot fly. Flightless birds are large-sized. They generally lack tail feathers. The keel of sternum is absent. Flightless birds include ostriches, rhea, emu, kiwi, and penguin. Ostrich is the largest living bird. It weighs about 157 kg. Ostriches are very good runners. They are found in Africa and Arabia. Rhea is found in South America. It is smaller than ostrich. Emu is found in Australia. It is smaller than rhea. Kiwi is found in New Zealand. It is Southern hemisphere (Antarctica). Their body is suited for diving and swimming.

Explanation:
In an experiment, a snail was observed to have moved a distance of 0.5 meters in 2 hours. What rate of movement was observed in this experiment?
The rate of movement was observed in this experiment as 0.25 m/ hour.
How, explain your answer?A rate of movement is essentially a speed measurement, where you divide the distance crossed from point A to point B by the time it took to do it.
o, we know the snail moved a total distance of 0.5 meters. that's our distance crossed.
We know that took 2 hours. so we just have to calculate that:
0.5 meters / 2 hours = 0.25 m/hour
