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.

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

The Answer Is "C"

Weather refers to the short-term atmospheric conditions, such as temperature, precipitation, humidity, wind speed, and cloud cover, that occur in a specific area over a short period of time, typically days or weeks.

Climate, on the other hand, refers to the long-term average weather patterns observed in a particular region over a period of decades to centuries.

Weather is the day-to-day variation in atmospheric conditions, including temperature, humidity, precipitation, wind speed, and cloud cover. It describes the current state of the atmosphere at a specific location and can change rapidly. For example, one day may be hot and sunny, while the next day may be cloudy and rainy. Weather conditions are influenced by various factors, such as air pressure systems, temperature gradients, and local geography.

Climate, on the other hand, represents the average weather patterns and conditions observed in a region over a long period of time. It is determined by factors such as latitude, elevation, ocean currents, and prevailing winds. Climate provides a broader perspective and encompasses the typical range of weather conditions experienced in a particular area. It takes into account long-term trends, seasonal variations, and averages of weather parameters.

While weather can change from day to day or even hour to hour, climate reflects the long-term patterns and trends in weather. For example, a region with consistently high temperatures and low rainfall throughout the year would have a hot and arid climate, regardless of occasional variations in daily weather conditions.

In summary, weather describes short-term atmospheric conditions, while climate represents the long-term average weather patterns observed in a specific area.

Answer:

Bone is a solid tissue, which resists a high impact of forces in its major axis.

The function of this fabric is not to transmit sounds, since it does not provide the elasticity, and the necessary elongation that is needed to generate the rope effect as in the case of muzzle cords.

Explanation:

The more rigid and less elastic the fabric is, the less sound it will transmit.

Sound strings, or mouth strings, are those that tighten, are flexible and resonate with different vibrations, in the case of bone tissue, sound vibrations are not influenced in their conformation because they do not have the ability to transmit them. .

The bone tissue, transmits impact forces or high newton levels, does not fulfill the function of transmitting vibrations and emitting sounds in terms of this type of vibrations and their frequencies.

Answer:

The correct answer is "Biogeography".

Explanation:

The missing options for this question are:

-Comparative embryology

-Biogeography

-Bioinformatics

-Fossils

The correct answer is "Biogeography".

Biogeography is a field of study focused on how species have changed over its evolutionary history regarding its distribution and geographical localization. Biogeography particularly examines biological diversity patterns. The evidence of evolution between the ostrich and the emu populations is of biogeographical type, since they are located in different regions but they are exposed to similar habitats.

The correct answer is Parents pass their physical traits to their offspring; those offspring with traits that help them survive in their environment are able to reproduce.

Explanation:

The modern theory of evolution explains the mechanisms that make organisms change. One of the main ideas this theory proposes is that organisms with traits that help them survive or reproduce have higher chances to pass their genes and traits to new generations. This mechanism makes certain traits to be favored and contributes to the evolution of organisms because after multiple generations certain traits will prevail while others will be eliminated.

Moreover, this theory specifies genes in an organism are not acquired or modified during its life but these are the results of the traits passed to the organism by its parents and evolution occurs only after a long time or multiple generations. According to this, the first option is the correct one.

answer: both aspects , sameness &variety are the result of biological evolution.

Answer:

At what rate do the mitochondria of the cell need to convert glucose to usable

energy molecules to meet the high energy needs of the cell?

Explanation:

Organelles are organ-like structures found in cells. The are responsible for the specific actions carried out by each cell. Each organelle has its own specific role to play. However, missing or damaged organelles can have effects on the cells.

Mitochondria are organelles found in cells of all eukaryotic living organisms e.g animal, plants as they are responsible for the synthesis of energy in form of ATP. Since the cells being investigated in this question is a MUSCLE CELL, which is only found in animals, then an appropriate organelle must be investigated.

The appropriate to be asked to know if muscles cells are functioning properly is: At what rate do the mitochondria of the cell need to convert glucose to usable energy molecules to meet the high energy needs of the cell?.

Note that, other options are incorrect because muscle cells do not have chloroplast and cell wall, while ribosomes are not site for glucose production.

Answer:

You type a text message, which your friend shows to a third party, who reacts to it.

Explanation:

Copied from google.

When a message is shown to a friend who shows it to another person.

A group of organs called glands makes up your endocrine system. These glands, which may be found all over your body, produce and emit hormones.

Hormones are substances that communicate with your organs, skin, muscles, and other tissues through your blood to coordinate various bodily activities. These messages instruct your body on what to do and when.

The level of hormones in your blood is regularly monitored by your endocrine system. In order to transmit the message, hormones send their messages by locking them into the cells they intend to reach.

When your hormone levels increase, the pituitary gland signals other glands to stop manufacturing and releasing hormones. The pituitary gland has the ability to tell other glands to manufacture and release additional hormones when levels fall below a specific threshold. Homeostasis is a mechanism that functions similarly to your home's thermostat. Almost every process in your body is impacted by hormones.

Therefore, it is like the scenario where a message is shown to a friend who shows it to another person.

Answer:

(c)volcanic eruption

Explanation:

An event that may lead to primary succession is volcanic eruption.

Primary succession happens when pioneer organisms colonize an area that holds no life before. It usually happens when a new land is formed or when a bare rock becomes exposed to life.

When volcanic eruption happens, new rocks are formed from the molten magma and these rocks provide a surface that can be colonized by pioneer species such as lichen.

From there, the successional process continues with time until a stable community is formed, all other things being equal.

ANSWER :

The deeper layers are too dark for photosynthesis to occur.

Explanation:

Photosynthesis is a unique process to autotophic organisms. It involves the use of light energy from the sun to manufacture organic molecules (food). As the phenomenon implies i.e. PHOTO - LiGHT, light is an unnegotiable requirement for photosynthesis to take place. Autotrophs are able to perform this process because they contain pigments (Chlorophyll) that can trap energy from sunlight.

In an aquatic ecosystem, phytoplanktons and other photosynthetic organisms like aquatic plants are the autotophic organisms. They are found in the upper layer of the water so that they can reach light from the sun. The light from the sun cannot travel deep down the water making the deep parts of the ocean be deprived of light.

This is the reason why photosynthetic organisms cannot be found in the deep parts of the water as they will be unable to have access to the light from the sun in order to perform photosynthesis.
