Answers
Answer:
Üçlü füzyonda, üçüncü bir sperm çekirdeği, embriyo kesesindeki merkezi hücre ile birleşerek endospermi üretir. Eşleşme ve üçlü füzyon arasındaki temel fark, eşleşmenin bir tür üretici döllenme olduğu, üçlü birleşme ise bir tür bitkisel döllenmedir .İyi Çalışmalar..
Answer:
Syngamy: Syngamy refers to the fusion of gametes in fertilization.
Triple Fusion: Triple fusion refers to the fusion of a sperm cell with the two polar nuclei during the double fertilization in angiosperms.
Type of Fusion
Syngamy: In syngamy, a male gamete fuses with a female gamete.
Triple Fusion: In triple fusion, a male gamete fuses with the central cell.
Result
Syngamy: Syngamy produces the zygote that develops into the embryo.
Triple fusion: Triple fusion produces the endosperm cell that develops into the endosperm.
Ploidy
PloidySyngamy: The result of the syngamy is diploid.
Triple Fusion: The result of the triple fusion is triploid.
Type of Gametes
Type of GametesSyngamy: Both male and female gametes are involved in the syngamy.
Triple Fusion: Only male gametes are involved in the triple fusion.
Type of Fertilization
Syngamy: Syngamy is a generative fertilization.
Triple Fusion: Triple fusion is a vegetative fertilization.
Occurrence
OccurrenceSyngamy: Syngamy occurs in animals and plants.
Triple Fusion: Triple fusion occurs in angiosperms.
Conclusion
Syngamy and triple fusion are two types of events in the sexual reproduction of plants. Syngamy is the fusion of male and female gamete, producing the zygote. Triple fusion is the fusion of a male gamete with the central cell of the female gametophyte, producing the endosperm. The main difference between syngamy and triple fusion is the type of fusion of cells in each event.

Explain how a. temperature and b. light intensity 0 affect the rate of transpiration.
Answers
Answer:
Explanation:
Transpiration can be regarded as process involving water movement through a plant, it involves evaporation from aerial parts. These aerial part could be such leaves, stems or flowers.
A)Temperature
During the day period when the weather is hot there would be increase in evaporation of water from the leaves of plants, due to this transpiration is increased
B)Light intensity
When there is bright light, when the light intensity heat the plants, the stomata would be opened so that carbon dioxide is supplied for photosynthesis, and more water would be evaporated out through the leaves of the plant, then transpiration increase
Describe all the tissues and cell types that are found in a leaf and describe how these individual parts work together to accomplish processes of photosynthesis.
Answers
Explanation:
While individual plant species are unique, all share a common structure: a plant body consisting of stems, roots, and leaves. They all transport water, minerals, and sugars produced through photosynthesis through the plant body in a similar manner. All plant species also respond to environmental factors, such as light, gravity, competition, temperature, and predation.

THANKS❤❤In three to five sentences, construct an argument that shows why lichens are necessary to establish a new ecosystem after an extreme disturbance.
I would really appreciate it if someone o two people would help me out on this one
Answers
Answer: Lichens affect every species in the ecosystem, in 2013 Russia had a dramatic lichen die off which caused 61,000, 20% of the entire reindeer population to die from starvation. And with fewer deers, the bears and wolves also suffered from the loss of lichens and if it takes a long time for lichens to grow back in an ecosystem, animal declines may take years if ever to be corrected. Lichens serve as a basis for several food chains, especially in artic communities.
The argument which shows why lichens are necessary to establish a new ecosystem is as follows;
Lichens are known to enable algae to live all over the world in many different climates.
On this note, lichens also provide a means to convert carbon dioxide in the atmosphere through photosynthesis into oxygen, a process required by all to survive.
Additionally, lichens provide us with valuable information about the environment around us.
On this basis, lichens are important for establishing a new ecosystem after an extreme disturbance.

Question 1/7 The Nile River carries sediments to the ocean. Over time, the sediments are compressed as more sediments are deposited on top of them. Which type of rock will be formed?
Answers
Answer:
Sedimentary Rock
Explanation:
Sedimentary rocks are formed from pieces of sediments or other existing organic matter or rock.
The sedimentary rock formation process begins with weathering which involves the breakdown of the sediments into small fragments. The next process is erosion, where water like the Nile River carries them to other places - in this case, the Ocean.
Over time, the sediments settle and become compressed as more sediments are deposited on top of them.
This leads to the formation of Sedimentary Rocks.

Answer:
The primary way that animals grow and develop is by building more cells. When an animal eats food, its body breaks the food down and uses it to fuel its energy requirements and build new cells through the process of mitosis. These new, or daughter, cells are often similar in size to the old, or parent, cells.

Answers
Answer:
The correct answer is d. the relationship between a person's mental health and the environment.
Explanation:
Ecopsychology is aimed at identifying the way in which the emotional aspects of human beings are influenced by the environment, that is, ecopsychology collects multiple experiences that connect human development with environmental awareness. Ecopsychologists are oriented to the search for the well-being of the human being through its connection with natural processes through the understanding of the complex interrelationships between people and the environment.

What is chromosome ?
A chromosome is a thread-like structure present in the nucleus of cells such as both prokaryotic and eukaryotic cell and it is made of a molecule of DNA (Deoxyribonucleic acid) and histone proteins.
It is composed of three components, DNA, proteins and RNA, amount of the DNA content ranges from 30 to 40 %, the amount of proteins from 50 to 65%, and small amount of RNA from 1 to 10%.
Two types of protein present in DNA such as histone and non-histones proteins, histone constitute large amount (90% of total protein), whereas non-histone is present in small amount (around 10% of total protein).
The histone protein is basic, whereas, the DNA is acidic, so it can be neutralized; DNA in chromosome is present in two forms such as Euchromatin and Heterochromatin.

1. Describe what occurs in the body of a type 1 diabetic after they consume a carbohydrate-heavy meal. In your response, include the following terms
Metabolized, Glucose, Insulin, Cell receptors, Pancreas, Energy
Answers
The process which would occur in the body of a type 1 diabetic after they consume a carbohydrate-heavy meal is:
The digestive system tries to break down the complex sugars which increases the blood sugar level which leads to the production of insulin to maintain the blood sugar level throughout the body.A Type 1 diabetic person is one who has been diagnosed with the level of diabetes, where the pancreas does not produce enough insulin to control the sugar levels of the body.
With this in mind, when such person consumes a high carbohydrate meal, it means that he has ingested complex sugars which would be difficult for the digestive system to break down which would overwork the pancreas, but as there is little or no insulin production, then there would likely be health complications.
