At which stage of development does the embryo implant in the uterus?
Answer:
Blastocyst stage
Explanation:
A baby undergoes different stages of development before they become fully matured. It all begins with the process of fertilization which involves a sperm cell coming in contact with an egg.
After a successful fertilization, the fertilized egg travels down to the uterus where it undergoes series of cell division till it becomes a stack of arranged cells known as the blastocyst.
During the blastocyst stage, the embryo fastens itself to the edge of the uterus, this process is known as implantation.
Hence, the embryo implants in the uterus during the blastocyst stage.

In Oxygen molecule O2, stability is gained through sharing of
Answer:
Trees and plants.
Explanation:
Trees give us oxygen and plants get rid of carbon dioxide and remake it as oxygen.
In the Oxygen molecule O2, stability is gained through sharing of two pairs of electrons with a single neighboring atom.
What is the sharing of electrons?The sharing of electrons gives rise to the formation of covalent bonds between two atoms. Atoms will be covalently bonded in order to gain more stability. During the process of sharing electrons, they are simultaneously attracted by the two atomic nuclei.
The stability of oxygen molecules is gained through the help of non-polar covalent bonds. This means that there is no difference in electronegativity of bonded atoms.
The valence shell of oxygen has six electrons, so they need two more electrons in order to fulfill its octet and maintain stability. The sharing and paring of electrons between two or more atoms construct a bond known as covalent bonds.
Therefore, in the Oxygen molecule O2, stability is gained through sharing of two pairs of electrons with a single neighboring atom.

ectotherm
endotherm
heterotrophs
species
Answer:
The correct answer is - endotherm.
Explanation:
Homeostasis is the process that is responsible for maintaining the internal body environment including the temperature of an individual in order to survive.
Endothermic organisms are the organism that maintains their body temperature and independent of environmental change where is ectothermic are dependent on the external environment to regulate their body temperature.
Thus, the correct answer is - endotherm.
Answer: Endotherm

Describe the type and ratio of organisms you would expect to find in a lake in a national park. give evidence to support your answer
Answer:
Algae would be the organism in greatest proportion in a lake in a national park.
Explanation:
A lake in a national park would have algae proliferation, which would be the largest organism in that lake. This is because a lake in a national park is subjected to great incidence of sunlight and large amounts of oxygen. This would facilitate and stimulate the reproduction of algae on a large scale, causing them to develop in the substrate, stones, pebbles, and in the water itself.
A farmer in Minnesota plants some tomato seeds in early spring. She plants them outdoors in soil and adds water every day. A few weeks later, nothing has happened. What is the most likely reason the seeds have not germinated?
Answer:
Other factors could affect the reason the seed didn't germinate because under suitable conditions depending on the variety it should germinate within 5 to 10 days from planting. However, the most likely reason it didn't germinate must be the Temperature.
Explanation:
From the question above, the farmer lives in Minnesota and she planted between March and May, meaning the temperature was way cold which is not suitable for tomato. One other valuable point was she planting outdoor which could also affect the performance of the tomato seedlings. Planting in early spring doesn't necessarily mean bad as some seeds might thrive under conditions explained above. For tomato, depending on temperature because too high temperatures could also affect the viability of the seeds. In Minnesota in early spring, it would have been better if she planted indoors to raise the temperature before transplanting as a balanced night temperature is also important for the seed viability.
Some other factors to be considered for seeds to germinate:
1. Water
2. Type of the soil
3. Seed depth in the soil
4. Nature of seed coat
5. Oxygen
6. Light

It was successful.
c.
It explained his theory of evolution.
d.
It was based on his findings in South Africa.
Answer:
The correct answer is option D. It was based on his findings in South Africa.
Explanation:
The theory of natural selection was first planned in Darwin's book "On the Origin of Species" in 1859, which is the process by which life forms change after some time because of changes in heritable physical or behavioral qualities.
His book On the Origin of Species took three years time to complete as he worked on the manuscript for three years. It was successful book. However, it was not based on his work on africa.

What exercise is most appropriate for testing muscular endurance?
A. Push-up
B. Bench press
C. Back squat
D. Bicep curl
Answer:
Push ups
Explanation:
Muscular endurance is when the muscle have the ability to withstand and sustain contractions that is constantly occur for a long period of time. It include the amount of repeated single exercise that the muscle can endure without resting. It ensures muscular fitness, muscular strength and power.
A good example of muscular exercise is push up the ability to constantly do it for a long time without rest or stopping.
The push-up is the most appropriate exercise for testing muscular endurance. Therefore, the correct option is A.
Muscular endurance is the ability of a muscle or group of muscles to sustain repeated contractions over a prolonged period of time.
The push-up specifically targets the chest, shoulders, triceps, and core muscles. It requires maintaining a plank position and lowering and raising the body by bending and extending the elbows.
By performing as many push-ups as possible without compromising form, an individual can assess their muscular endurance level.
