.Explicati de ce algele pluricelulare au culoarea rosie,verde respectiv bruna ?
Answer:
Due to different pigments.
Explanation:
The multicellular algae are red, green and brown because of the presence of pigments. The red algae are red in colour because of the presence of the phycoerythrin which is a type of pigment. This pigment reflects red light due to already presence in its body and absorbs blue light that is necessary for photosynthesis process. The brown algae contain fucoxanthin pigment and green algae contain xanthophylls pigments that are responsible for its colour so we can conclude that these different types of pigments are responsible for the different colour of algae.

Select ALL of the following genotypes below that respresent males.
XXY
XX
XYY
XXX
XY
Answer:
Is it XXX that all males want?
Explanation:
Just joking! I still think it is XXY
The genotype that represents males is XY of 50 % of both X and Y chromosomes where a slight change in the alignment might cause to chromosomal disorders .
XXY , XYY , XY represents males genotypes.
What are chromosomal disorders ?
These are the disorders which are associated with the change in the normal XY sequence of males. Various disorders and syndromes are associated with the mutation and the responsible factor can be trisomy like.
XXY is a chromosomal mutation found in the males only called as Jacob syndrome, XYY is a chromosomal disorder called as klinefelter syndrome found in males only.
XX is the genotype of a female, XXX is a condition that affects 1 in every 1000 females.
Thus, except XX and XXX is the exception as both of these represent females.

What is an example of weathering, erosion, and deposition in Texas? (A)Gradual change to Guadalupe Peak (B)All of the above (C)The changing coastline of Texas (D)The creation of Palo Duro Canyon
Answer: Weathering, erosion, and deposition from the terrestrial surface topography and soil characteristics. These processes, for example, have formed a variety of landforms in Texas like beaches, plateaus, mountains, and canyons as well as soil types like fertile soil, clay-rich soil, and sandy soil. The combination of topography, soil, and climatic conditions in an area defines the types of habitats that the area can support this is crucial to ecoregion classification. Ten separate ecoregions occur in Texas including 1) East Texas Pineywoods, 2) Gulf Coast Prairies and Marshes, 3) Oak Woods and Prairies, 4) Blackland Prairie, 5) cross timbers and prairies (6) Rolling Plains, (7) High Plains, (8) TransPecos, (9) South Texas Plains, (Brush Country), and (10) Edwards Plateau. Such ecoregions are named for the major types of habitats topographical features (e.g. Edwards Plateau) present in their areas. The weathering, erosion, and deposition of each of these ecoregions have an important influence. Hope This Helps :)

What are two ways you know a chemical reaction has taken place?
Plants, like all organisms, adapt to the conditions of their environment. Some special challenges a plant may face are drought, flooding, and a salty environment. Your task is to identify and describe ways that plants adapt to these challenging conditions in their environment. Select one plant adaptation to drought, one adaptation to flooding, and one for salt tolerance. Explain how each adaptation enhances plant survival. Identify a scholarly source of information for each. Use quotes appropriately; be sure your responses are written in your own words
Answer:
Hydrophytes is flood tolerant plants, barley is salt tolerant crop and sorghum is a drought tolerant crop.
Explanation:
Hydrophytes also known as flood tolerant plants that have adaptations to survive flood problems. The plant has the development of air spaces in the roots and stems which allow diffusion of oxygen from the aerial portions of the plant into the roots. Barley shows a greater degree of salt tolerance by applying method of osmoregulation which helps the plant to tolerate salt stress. Sorghum is a plant that is adapted to drought condition. These plants have less number of stomata and waxy layers on the leaves which lowers the rate of evaporation or transpiration.
3. In tropical regions,
a, a permanent thermocline traps nutrients in the deep water
b. primary productivity is high all year round, because there is a constant supply of solar energy for
photosynthesis
c, the thermocline disappears in the winter
d. the upper and lower layers of water mix all year round
Answer:
a, a permanent thermocline traps nutrients in the deep water
b. primary productivity is high all year round, because there is a constant supply of solar energy for photosynthesis.
Explanation:
Thermocline occurs in the tropical regions because the temperature is very high which warms the upper layer of water bodies whereas the lower layer of water has low temperature due to no sunlight. The primary productivity is high all year in the tropical regions, because there is a constant supply of sunlight that is needed by the plants for preparing their own food.

Using the Punnett Square for the Rr x Rr cross, what percentage of the offspring are going to be heterozygous?
100%
50%
0%
75%
Answer:
50%
Explanation:
The punnet square gives you a 25 percent probability of RR, a 50 percent probability for Rr, and a 25 percent probability for rr. Rr is the only option heterozygous
Using the Punnett Square for the Rr x Rr cross, 50% of the offspring are going to be heterozygous. Thus, the correct option is Option B.
What is a Punnett Square?The Punnett square is a square diagram used to predict genotypes of a specific cross or breeding experiment. It is named after Reginald C. Punnett, who invented it in 1905. Biologists use the diagram to calculate the likelihood of an offspring having a specific genotype.
The Punnett square is a table that lists all possible combinations of maternal and paternal alleles. These tables can be used to investigate the genotypical outcomes of offspring of a single trait (allele) or when crossing multiple traits from the parents. The Punnett square represents Mendelian inheritance visually.
Therefore, 50% of the of the offspring are going to be heterozygous or the Rr x Rr cross, using the Punnett Square.

Name 2 ways wind energy is used to move objects.
Name 2 ways water energy is used to move objects.
Answer:
Wind - Humans use this wind flow, or motion energy, for many purposes: sailing, flying a kite, and even generating electricity. ... The difference in air pressure across the two sides of the blade creates both lift and drag. The force of the lift is stronger than the drag and this causes the rotor to spin.
Water - The energy from moving water can be used to create electricity in several different ways. For example: A hydroelectric dam captures energy from the movement of a river. Dam operators control the flow of water and the amount of electricity produced

Metagenomics (check all that apply): Group of answer choices Can leverage Next Generation Sequencing technology to identify and characterize organisms. Rarely finds previously unknown microorganisms. Has resources to support analysis at the DOE-JGI site. Can identify microbiologic organisms without traditional isolation and culturing of individual organisms.
Answer:
- Can leverage Next Generation Sequencing technology to identify and characterize organisms
- Has resources to support analysis at the DOE-JGI site.
- Can identify microbiologic organisms without traditional isolation and culturing of individual organisms.
Explanation:
Metagenomics can be defined as the study of whole genomes of biological communities recovered from environmental samples. This genomic field has enabled the discovery of new species (microorganisms) and their effects on the environment. Next-Generation Sequencing (NGS) technologies allow to obtain huge amounts of genomic data, which has been a limitation in genomics and metagenomics. Metagenomic NGS (mNGS) is a technique used for sequencing nucleic acids present in a biological sample containing mixed populations of microorganisms. Finally, the Department of Energy Joint Genome Institute (DOE JGI) is a referent in metagenomic analysis, especially in genome assembly data obtained from microbial communities. This Science User Facility has developed a series of bioinformatics tools and databases in order to analyze metagenomic information.
A 15 mL sample of gasoline has a mass of 11 g. What is the density of the gasoline?
The density of gasoline with a mass of 11g and volume of 15mL is 0.733g/mL.
DENSITY:The density of a substance can be calculated by dividing the mass of the substance by its volume. That is;Density = mass ÷ volume
According to this question, a 15 mL sample of gasoline has a mass of 11 g. The density of gasoline is calculated as follows:Density = 11g ÷ 15mL
Density = 0.733g/mL
