Answer: Angiosperms are the plants which produce flowers for sexual reproduction.
Explanation:
In the angiosperm life cycle the following events occur:
1. Seed germination: Under suitable condition inside the soil obtain water, oxygen and minerals the seed germinates and from the two precursors plumule from where the stem emerge and radicle from where the root emerges.
2. Mature plant with flower: The plant gets matured with the develop of root and shoot and from the shoot the bud originates which produces the flower.
3. Pollination: During the process of pollination a mature pollen grain is transferred towards the female reproductive structure typically the stigma receives the pollen grain.
3. Fertilization of pollen with egg in ovary: The pollen is the male gametophyte which develops in the anthers which are the male reproductive structure of the flower and the egg or ovule is the female gamete which develops inside the ovary or female gametophyte. The fusion of male gametes provided by the pollen grain with that of the ovule is called as fertilization.
4. Formation of fruit with seed: After the fertilization process the ovules develop into seed and the ovary into fruit.
5. Seed dispersal: The fruit gets detached from the plant and it may get rotten and dried the dried seeds disperse and may germinate in favorable conditions.
What is the melting point of ice?
Answer:
32°F
Explanation:
The melting point is the temperature at which a solid turns to a liquid. The melting point at which ice — a solid — turns to water — a liquid — is 32°F (0°C). Invite the children to record their responses in their Ice Investigator Journals.
Name and describe 3 major characteristics of vascular plants?
Answer:
Roots. Roots are simple tissues that are derived from the stem of the plant.
Xylem. The xylem is tissue that transports water throughout the plant.
Phloem. The phloem is the plant's food transportation system.
:)
Three major characteristics of vascular plants are, roots are simple tissues that are derived from the stem of the plant, Xylem is the tissue that transports water throughout the plant, and phloem is the plant's food transportation system.
What is the vascular plant?The vascular plants are also called tracheophytes. These are all land plants that have special lignified tissues that conduct water and minerals.
The major characteristics of vascular plants are specialized tissues for consuming minerals and water.
Thus, the stem of the plant derived roots, are basic tissues that carry nutrients throughout the plant. Xylem is the tissue that carries water throughout the plant. Phloem is the tissue that carries water throughout the plant.

What are potential impacts on society and the environment of using a genetic approach to improving food productivity? Do you think this is how we should fix the worlds hunger problem? Why or why not? Please explain…
Answer:
- Society: the use of genetic improving techniques may have a positive impact through crop improvement of traits of agronomic importance such as, for example, resistance to biotic and abiotic stresses.
- Environment: the development of genetically modified crops conferring resistance to pesticides may have a negative effect on wildlife species (both plants and animals) and humans living in such agroecosystems.
Explanation:
In crops, genetic improvement technologies can be defined as the techniques associated with the development of better crop varieties, i.e., varieties that have higher grain yield, produce more biofuel, higher fiber content, etc. Genetic improvement techniques include, among others, selective breeding and genetically modified organisms. In crops, genetic improvement techniques have the potential to reduce hunger in the world. However, it is important to note that genetic engineering may be associated with the horizontal transference of genes and the development of genetically modified organisms (GMO), which may have harmful effects on wildlife species and humans, thereby GMO crops must be carefully assessed before their release into the field.

If you've just completed a long hike, marathon, bicycle ride or other extended form of high-intensity exercise, you could experience temporary dips in your blood glucose levels. Glucose level lower than 70 mg/dl is called hypoglycemia and can result in extreme hunger, depression, headaches, an uncontrollable craving for sweets, or heart palpitations. The good news is that these symptoms are easily rectified by eating something sweet. Eating 4 - 6g of a highly concentrated glucose product like hard candy or fruit juice should get you back on your feet within 20 to 30 minutes. Using this recommendation, what is the minimum number of calories needed to bounce back after the workout?
A
1-15 calories
B
100-200 calories
C
16-24 calories
D
36-54 calories
Answer:
(c) 16-24 calories
Explanation:
In the question it is provided that 4 - 6g of highly concentrated glucose product helps to get on the feet within 20 to 30 minutes.
Also we know that 1 gram of glucose contains 4 calories.
Therefore,
4g of glucose = 4 × 4 calorie
= 16 calories
6g of glucose = 6 × 4 calorie
= 24 calories
Thus, we can say that the minimum number of calories needed to bounce back after the workout is 16 - 24 calories
Hence, the correct answer is option (c) 16-24 calories

To calculate the speed of wave, what two pieces of information do you need about the wave ?
help asap plz i’m being timed!!!
Answer:
Wavelength and Frequency
Explanation:
The speed of a wave can be related to the speed of an object which is calculated using:
[tex]Speed = \frac{Distance}{Time}[/tex]
So: the speed of a wave (v) is calculated using:
[tex]v = f * L[/tex]
Where:
[tex]f= Frequency[/tex]
[tex]L = Wavelength[/tex]
Frequency is calculated as:
[tex]f = \frac{1}{T}[/tex]
Where:
[tex]T = Period[/tex]
This means that the two basic information needed are the wavelength and the frequency of the wave

A gene includes the sequence AGAACT. When it is transcribed, what will the RNA sequence be? A. UCUUGA B. UGCCGU C. UCUUTC D. TCTTGA
Answer:
A
Explanation:
The correct option would be A.
According to the base-pairing rule, Adenine (A) always pairs with Thymine (T) (or Uracil in the case of RNA) while Guanine (G) always pairs with Cytosine (C).
Hence;
A-U
G-C
A-U
A-U
C-G
T-A
Therefore, AGAACT would be transcribed to UCUUGA.

Answer:
Comparison Chart
BASIS FOR COMPARISON SOLID LIQUID GAS
Meaning Solid refers to a form of matter which has structural rigidity and has a firm shape which cannot be changed easily. Liquid is a substance, that flows freely, having a definite volume but no permanent shape. Gas refers to a state of matter, do not have any shape but conform to the shape of the container, completely, in which it is put in.
Shape and Volume Fixed shape and volume. No fixed shape but has volume. Neither definite shape nor volume.
Energy Lowest Medium Highest
Compressibility Difficult Nearly difficult Easy
Arrangement of molecules Regular and closely arranged. Random and little sparsely arranged. Random and more sparsely arranged.
Fluidity Cannot flow Flows from higher to lower level. Flows in all directions.
Molecular motion Negligible molecular motion Brownian molecular motion Free, constant and random molecular motion.
Intermolecular space Very less More Large
Intermolecular attraction Maximum Medium Minimum
Sound speed Fastest Faster than gas but slower than solid Lowest among all
Storage Don't need container, for storage. Cannot be stored without container. Needs closed container for storage.
