how to cultivate yam
Explanation:
Yams are produced through slips, which have been generated again from sprouts of mature yams, rather than seeds, as most other crops are. Split a yam in part and place one half in a bowl of cool water to develop sprouts.

Why is it important for nitrogen to be more abundant in our atmosphere than oxygen?
A. Oxygen is only breathable if diluted with nitrogen.
B. Nitrogen and oxygen combine to produce weather that is essential for life.
C. Oxygen must be diluted because it is a highly combustible gas.
D. Nitrogen is a heavy molecule that pulls oxygen, a light molecule, to the surface for oxygen-dependent life to use.

Paleoclimatic analysis has generated a claim that there is a possible correlation between an extinction event around 29 million years ago that allowed grasslands to become abundant and the adaptive radiation of several groups of butterflies.
Which of the following proposes the best alternative hypothesis for the claim?
A- Climate analysis conducted by sampling pollen preserved in amber shows an increase in grass pollen 29 million years ago, but there is no significant difference between speciation rate, as well as species richness with regard to butterflies, before and after 29 million years ago.
B- Climate analysis conducted by sampling pollen preserved in amber shows an increase in grass pollen 29 million years ago, which indicates there was an increase in grasslands that correlates to an increase in butterfly speciation during the same time period.
C- There is a correlation between the rapid and wide-ranging decrease in species richness of insects in general 29 million years ago and the increase in species richness and diversity among the butterfly population during the same time period.
D- Evidence of rapid speciation among butterfly species 29 million years ago is evenly distributed among all environments of that period.

What is parturtion and lactation???
Answer:
It is the process of production of milk by the mammary glands at the end of pregnancy. The milk produced initially by the glands is called colostrum. This milk is crucial for the baby as it provides the child with the initial immunity. This was a brief explanation of pregnancy, parturition, and lactation.

Biomes are determined by
Answer:
Biomes are determined by their climate which is determined by percipitation and temperature
Explanation:
There are two main factors when scientists define a biome. One is the climate or the long-time average weather of a region. The other is the specific plants and animals in an area. The organisms in a biome often adapt to their environment. There are seven types of biomes based on these factors.

Explanation: Fungi reproduce by spores, they are enclosed by cell walls, they have a nucleus as they are eukaryotic, and they are heterotrophs as they do not contain chloroplasts
Starting with spore dispersal, and identify adaptations in the life cycle of the bryophyte for living in a terrestrial environment (ie, in air, without water surrounding the plant body). What are new stresses associated with living on land, and what morphological or physiological features did the first land plants have to evolve to cope with these stresses
Answer:
Stresses such as lack of nutrients, space, competition and water availability.
Explanation:
Lack of nutrients, space, competition and water availability are the stresses that the bryophyte can experience by living on land. The morphological or physiological features such as lowering transpiration rate by stomata, attain specialized structures to collect sunlight and fulfill water requirement by absorbing water from the air if no water is available in the soil etc are the features that the plant has to attain to cope with these stresses.
what are the limitations of cell theory
Answer:
The shortcomings or drawbacks of cell theory are: Viruses are considered as acellular entities or organisms that do not have cell machinery, yet they are taken into account as organisms in this cell theory. Matthias Schleiden and Theodor Schwann did not know the mechanism of the cell.

How do elephants warn their family groups of a dangerous predator in their habitat?
A. They use their trunks to make loud sounds.
B. They stomp their feet to create noise.
C. They use their tusks to kick up dirt.
D. They flap their ears rapidly.
Answer:
How do elephants warn each other?
When they're excited, scared or happy, elephants make the trumpeting sounds you're probably familiar with. They vocalize in other, more complicated ways, too — low-pitched rumbles outside our range of hearing. At less than 20 hertz, these infrasonic calls are often used to alert each other to danger.

The first phase of Mitosis is _________ . In this phase the DNA condenses down into ________, and the duplicated separate. The second phase of Mitosis is_______ . In this phase the sister chromatids line up on the _______ plate through a push and pull motion as they connect to the microtubule spindle fibers emanating from the ________. The third phase of Mitosis is________ . In this phase the________ (sister chromatids or homologous chromosomes) are pulled apart. The fourth phase of Mitosis is_______ . In this phase the nuclear ________starts to reform and the DNA de-condenses.
MITOSIS:
This question is describing the process of mitosis, a kind of cell division that results in two genetically identical daughter cells. Mitosis consists of four stages namely: prophase, metaphase, anaphase, and telophase etc. PROPHASE is the first stage of mitosis where DNA condenses down into CHROMOSOMES, and the duplicated separate.METAPHASE is characterized by the lining up of sister chromatids at the CELL PLATE through a push and pull motion as they connect to the microtubule spindle fibers emanating from the CENTROSOME. ANAPHASE is the third stage of mitosis in which duplicated chromosome/sister chromatids are pulled apart into opposite poles. The fourth stage is TELOPHASE where the NUCLEAR MEMBRANE starts to reform and the DNA de-condenses.Learn more at: https://brainly.com/question/3327479?referrer=searchResults

Answer:
is the site where lipids destined for other cellular compartments are manufactured.
Explanation:
This is because smooth endoplasmic recticulum is an organelles found in eukaryotic organisms that lack membrane bound ribosomes and are found in cells that has much lipids like ovaries, testes, oil glands in the skin e.t.c. They are important in the synthesis of lipids is the site where lipids , Phospholipids, steroid hormones.
They also play a major role in detoxification of harmful metabolic by products and metabolic processes of calcium ions within the cell
